“If you focus on something long enough, it will come to you.” Sounds like the Law of Attraction, right? But in 2025, this has a whole new face — and it’s powered by AI algorithms. The idea is simple: Focus your mind on what you want. The universe will align to make it happen. Believers say: 易 “Thoughts become things.” Let’s bring in Instagram, Facebook, or YouTube: Don’t like a post? No problem. Just pause for a few seconds, and BAM — the algorithm picks it up. Now your feed is filled with related posts, ads, and suggestions. It feels like magic. But it’s not. Every interaction you make: Scroll Click Pause Comment …is stored, tracked, and processed. The algorithm uses machine learning to analyze your behavior — and shows you more of what you seem to like. Just like “manifesting,” right? Concept Law of Attraction Social Media Algorithm Source Belief / Energy Data / Behavior Trigger Focused Thought Interaction Time Outcome Universe Responds Feed Optimization Based on Faith AI & ML Models We’re no longer manifesting with just thoughts. We’re training machines with our attention. So next time something "just appears" in your feed — don’t thank the universe.

I've created a "tune API" for the next version of VarMQ. Essentially, "Tune" allows you to increase or decrease the size of the worker/thread pool at runtime. For example, when the load on your server is high, you'll need to process more concurrent jobs. Conversely, when the load is low, you don't need as many workers, because workers consume resources. Therefore, based on your custom logic, you can dynamically change the worker pool size using this tune API. In this video, I've enqueued 1000 jobs into VarMQ, and I've set the initial worker pool size to 10 (the concurrency value). Every second, using the tune API, I'm increasing the worker pool size by 10 until it reaches 100. Once it reaches a size of 100, then I start removing 10 workers at a time from the pool. This way, I'm decreasing and then increasing the worker pool size. Cool, right? VarMQ primarily uses an Event-Loop internally to handle this concurrency. This event loop checks if there are any pending jobs in the queue and if any workers are available in the worker pool. If there are, it distributes jobs to all available workers and then goes back into sleep mode. When a worker becomes free, it then tells the event loop, "Hey, I'm free now; if you have any jobs, you can give them to me." The event loop then checks again if there are any pending jobs in the queue. If there are, it continues to distribute them to the workers. This is VarMQ's concurrency model.  ( 3 min )

In modern React development, user interactivity is everything. Mouse events form the core of how users engage with your components—from clicking a button, dragging a file, to hovering over content for context. In this article, we’ll deep dive into the wide array of mouse and drag-related event handlers available in React + TypeScript. We'll explore their purpose, use cases, and demonstrate best practices through an interactive math-based UI. Whether it's clicking a calculator button or dragging a number into a math equation, mouse events allow users to manipulate the UI directly. Mastering these events allows you to build: Custom context menus Drag-and-drop editors Interactive games Advanced canvas-based charts React uses a synthetic event system—a cross-browser wrapper around the browser’…  ( 4 min )

When people hear "software engineer," the first image that pops into their mind is someone furiously typing code, probably in a dark room with six monitors and a cup of cold coffee. But is that all there is to it? Not even close. In this post, let’s explore what it really means to be a software engineer — beyond the code. Being a great software engineer isn’t just about knowing 12 different JavaScript frameworks. It's about understanding problems and communicating solutions. Can you explain a complex bug to your product manager in simple terms? Can you write clear, helpful documentation? Can you give constructive feedback in code reviews? 💡 If you're not improving your communication skills, you're limiting your growth. You’ll often face challenges that have nothing to do with code: Ambiguous requirements Legacy systems with no documentation Interpersonal team conflicts Sometimes, you spend more time on Slack than in VS Code. And that’s okay. That’s part of the job. You don't just learn programming languages — you learn people, processes, and priorities. The most successful engineers I've met are not the ones who knew everything — but the ones who kept learning every day. Burnout is real. Sleep deprivation doesn’t make you a hero. Take breaks. Set boundaries. Eat lunch away from your screen. Because your brain is your best asset — and it needs rest to work its magic. Software engineering is a journey — and the code is just one part of it. The next time someone asks you what you do, don’t just say "I write code." Because that’s what you really do. 💬 What’s something you've learned outside of code that made you a better developer? Drop your thoughts below — let's talk!  ( 4 min )

Understanding DNS: How Domain Names Become IP Addresses In our previous blog post, we covered domains and their various aspects. Now, let's dive deeper into DNS (Domain Name System) - the backbone of internet navigation. DNS, or Domain Name System, is essentially a translator for the internet. Its primary function is simple yet crucial: it converts human-friendly domain names (like example.com) into machine-readable IP addresses that computers use to identify each other. Without DNS, you'd need to memorize numeric IP addresses instead of easy-to-remember domain names. Before we explore how DNS works, let's clarify two important roles that make the domain system possible: A registry is an organization that manages a specific top-level domain (TLD) For example, Verisign manages the .com an…  ( 8 min )

HTTP HTTP (Hypertext Transfer Protocol) is a protocol used for exchanging data over the web. Loading product lists Fetching user profiles Checking order status RESTful APIs RESTful(Representational State Transfer) is an architectural style for designing web services (APIs). ✔ Resource-based URLs (/users, /products) ✔ Stateless (no client data stored between requests) ✔ JSON/XML responses ✔ Standard HTTP methods Client-Server Architecture : Backend (API) and frontend (UI) should be completely separate. Stateless : Each request must contain all necessary authentication/authorization data. Cacheable : Responses (especially GET requests) should be cacheable. Uniform Interface : Resource access must follow consistent and clear rules. Layered System : The client should never directly access the database.

United Kingdom crypto companies will need to collect and report data from every customer trade and transfer beginning Jan. 1, 2026 as part of a broader effort to improve crypto tax reporting, the UK government said. Everything from the user’s full name, home address and tax identification number will need to be collected and reported for every transaction, including the cryptocurrency used and the amount moved, the UK Revenue and Customs department said in a May 14 statement. Details of companies, trusts and charities transacting on crypto platforms will also need to be reported. Failure to comply or inaccurate reporting may incur penalties of up to 300 British pounds ($398.4) per user. The UK Revenue and Customs department said it would inform companies on how to comply with the incoming …

Hong Kong police arrested 12 people involved in a cross-border money laundering scheme that relied on crypto and over 500 stooge bank accounts to launder HK$118 million ($15 million), local news outlets reported. The syndicate was dismantled on May 15, resulting in the arrest of nine men and three women in mainland China and Hong Kong. The suspects allegedly recruited others to open bank accounts to receive proceeds from fraud cases, which were then converted into crypto at crypto exchange shops to launder the illicit funds, Hong Kong Commercial Daily reported on May 17. The criminal organization rented a residential unit in the Hong Kong neighborhood of Mong Kok to plan and carry out its money laundering activities. Of the $15 million laundered, more than $1.2 million was linked to 58 re…

Buy Me a Coffee☕ *Memos: My post explains variable assignment. My post explains iterable unpacking in variable assignment. My post explains parameters and arguments. My post explains positional-only parameters in function. My post explains keyword-only parameters in function. My post explains positional-only parameters and keyword-only parameters together in function. Lambda: is the function which can be stored in a variable and parameter. is an expression. cannot be used with pass. is almost same as a normal function except these above. You can see Lambda Expressions You can use Lambda as shown below: # Equivalent v1 = lambda: 2 # def func(): return 2 v1 = lambda x: x # def func(x): return x v1 = lambda x, y: x+y # def func(x, y): return x+y v1 = lambda x, y=3: x+y # def func(x, y=3): return x+y v1 = lambda x=2, y=3: x+y # def func(x=2, y=3): return x+y v1 = lambda x=2, /, y=3, *, z=4: x+y+z # def func(x=2, /, y=3, *, z=4): # No error # return x+y+z v1 = v2 = lambda: 2 v1, v2 = [lambda: 2, lambda: 3] # No error v1 = lambda: pass v1 = def func() return 2 v1 = func() return 2 # SyntaxError: invalid syntax v1 = lambda: 2 print(v1()) # 2 v1 = lambda x: x print(v1(2)) # 2 print(v1(x=2)) # 2 v1 = lambda x, y: x+y print(v1(2, 3)) # 5 print(v1(2, y=3)) # 5 print(v1(x=2, y=3)) # 5 print(v1(y=3, x=2)) # 5 v1 = lambda x=2, y=3: x+y print(v1(6)) # 9 print(v1(x=6)) # 9 print(v1(y=5)) # 7 print(v1(6, 5)) # 11 print(v1(6, y=5)) # 11 print(v1(x=6, y=5)) # 11 print(v1(y=5, x=6)) # 11 v1 = lambda x=2, /, y=3, *, z=4: x+y+z print(v1(6, 5, z=4)) # 15 print(v1(6, y=5, z=4)) # 15 print(v1(6, z=4, y=5)) # 15 v1 = v2 = lambda: 2 print(v1(), v2()) # 2 2 v1, v2 = [lambda: 2, lambda: 3] print(v1(), v2()) # 2 3 def func(x=lambda: 2): print(x()) func() # 2 func(lambda: 4) # 4 func(x=lambda: 4) # 4  ( 4 min )

Domains are to the internet what names are to humans, making identification simple and intuitive for everyone. Just as we give people names instead of describing their physical characteristics each time we refer to them, domains give websites and online resources readable names instead of complex numerical addresses. When you type 'google.com' instead of having to remember a string of numbers like '172.217.168.238', you're benefiting from the domain name system that makes the internet accessible to everyone. One key difference from human names is that while many people can share the same name in the real world, a single domain can only point to one destination at a time on the internet. However, you can have multiple domains all pointing to the same resource, similar to having several nick…  ( 9 min )

Chapter 1: The Birth of a Visionary (Pre-1994) The early 1990s were a time of tectonic shifts in both politics and technology. The Cold War had just ended, giving way to a wave of globalization. Meanwhile, the internet, once a military and academic curiosity, was on the verge of becoming commercially viable. In 1990, Tim Berners-Lee introduced the World Wide Web, and by 1993, web browsers like Mosaic were making the internet accessible to the average user. Amid this digital dawn, a Wall Street executive named Jeff Bezos was working at D.E. Shaw, a prestigious hedge fund. Bezos, a Princeton graduate with a background in computer science and electrical engineering, came across a stat that changed everything: internet usage was growing at 2,300% per year. Bezos immediately recognized the co…  ( 6 min )

Hello Dev.to community! 👋 I’m excited to share my journey as a developer and how I managed to improve my coding skills significantly by focusing on building small practical projects. Here are some tips that worked for me: Start small: Don’t try to build complex apps from day one. Begin with simple projects like a to-do list or a calculator. Practice regularly: Dedicate at least 30 minutes every day to coding. Learn from mistakes: Don’t be afraid to break your code. Debugging is a great way to learn. Use online resources: Platforms like freeCodeCamp, MDN, and Stack Overflow are fantastic. Share your code: Use GitHub or Dev.to to share your projects. Getting feedback helps you improve. If you’re starting your coding journey or looking for motivation, keep pushing forward — consistency is key! Feel free to follow me for more coding tips and project ideas. Let’s grow together! 🚀  ( 3 min )

In Go, the Option pattern (also known as the configuration pattern or constructor pattern) is a commonly used design pattern, primarily for handling function parameters, especially when a function has many optional parameters. By using the Option pattern, we can pass and configure function parameters in a flexible and extensible way, avoiding the maintenance challenges and complexity of traditional methods with too many parameters. Let’s take a look at how the Option pattern is used in Go, analyze its implementation principles, and help you better understand how to apply this pattern in real-world projects. When constructing complex objects in Go, we often encounter the following pain points: // Example problem: Parameter explosion and difficult maintenance func NewServer(addr string, port…  ( 6 min )

Predictability, Pre-Recorded Reality, and AI Evolution: From Dilbert to LivinGrimoire Are We Just Predictable Scripts? The Dilbert Dilemma In an episode of Dilbert, the protagonist unwittingly has a conversation—not with his mother, but with a recording of her usual responses. She had pre-recorded their exchanges because Dilbert was so predictable, his side of the conversation could be anticipated without her present. Even when Dilbert realized he was talking to a recording, it kept responding accurately to him, as though their conversation were still fluid and natural. This presents a stunning thought experiment: how could Dilbert prove he was talking to a recording? What test could he run to confirm whether the responses were truly dynamic or just well-constructed predictions? …  ( 5 min )

🌍 A Bit of History — Where HTTP Came From Back in 1989, Tim Berners-Lee invented the World Wide Web (WWW). But it wasn’t just websites — it was a system of protocols, and one of them was HTTP: the HyperText Transfer Protocol. HTTP was designed as a simple way to send hypertext (HTML) documents between computers. This allowed the user to experience a more dynamic and interactive way to access information. Since then, HTTP has evolved (currently at HTTP/3), but its core idea hasn’t changed: "Let the client ask, and let the server answer." That basic principle powers nearly every web app today. Without HTTP, the internet would not look, feel, or behave as it does. 📸 Request vs response: When your browser opens a website, it sends an HTTP request. The server replies with an HTTP respo…  ( 4 min )

A Quick Guide to Getting LinkedIn OAuth Working Correctly LinkedIn authentication is a powerful feature to add to your Next.js application using NextAuth.js, but the default configuration can often lead to issues — especially when trying to fetch user details like email, name, and profile picture.

Supabase Auth already has an Auth Users table. The image might be blurry. If you visit the project in your Supabase Account, you can check your Auth table of the project. If you wanted to add additional data to your a User table, it's likely you've wondered 🤔 Should you create your own, separate profiles (or users) table in Supabase and link it with the Supabase Auth Users table? OR Should you extend the existing Supabase Auth Users table? Supabase’s recommended pattern is to create a separate profiles (or users) table in the public schema rather than altering the built-in auth.users table. The auth.users table (in the auth schema) is managed internally and isn’t exposed via the auto-generated API. Supabase maintainers explicitly advise “It is not recommended to modify the schema…  ( 4 min )

If you're using Rancher Desktop and ran into this error when running supabase start: supabase_vector_project container is not ready: unhealthy You're not alone — and here's what likely caused it (and how to fix it): Supabase CLI uses Docker under the hood, and it expects to communicate with the Docker Engine via a well-behaved socket or TCP endpoint. Rancher Desktop (especially with containerd or non-default networking setups) can cause issues with: Port forwarding DNS resolution Health checks (like with the vector container) This often results in the vector container going into an unhealthy state, crashing the entire setup. I recommend switching to Docker Desktop if you're planning to use Supabase CLI locally. On Docker Desktop: Supabase CLI is better supported and more stable If needed, enable: "Expose daemon on tcp://localhost:2375 without TLS" (from Docker Desktop settings → General) This change instantly fixed the issue for me. Hope this saves someone hours of debugging. Feel free to comment if you've found a better way!  ( 3 min )

Just because AI tokens are cheap today doesn’t mean they’ll stay that way. When cloud adoption peaked around 2015, everyone migrated to “save money.” But many teams didn’t fully understand their on-prem costs, nor did they have a realistic plan for managing spend once they migrated. It’s as though we forgot about all our best practices. In 2015, cloud spend was projected to grow from $49B to $67B by 2018. In 2023? It hit $563.6 billion, with $678.8 billion forecasted for 2024 Alongside that growth came tool sprawl, security risk, and unexpected costs. Sound familiar? AI token usage is on a similar path only this time, the underlying mechanics are even more opaque. Let’s demystify it. A “token” is just a chunk of text (words, punctuation, etc.) that an AI model processes. But the cost and i…  ( 5 min )

The first time I encountered state management in Vue, I was overwhelmed. I was building a simple dashboard application that had grown from a weekend project into something much more complex. Components were passing props six levels deep, and emitting events that would get lost in the hierarchy. I remember thinking, "There has to be a better way." That's when I discovered Vuex. It felt like finding an oasis in the desert. But as time passed and my projects grew more complex, I started to feel the pain points. The boilerplate code, the mutations that seemed redundant, the TypeScript support that always felt a bit bolted on rather than built-in. Then came Pinia, and it was like a breath of fresh air.

Will Ai replace programmers" by AI The idea that "AI will replace programmers" is a hot (and often exaggerated) debate. Here’s my take: AI Won’t Replace Programmers—But It Will Change the Job. -AI is a tool, not a replacement. Just like calculators didn’t replace mathematicians, AI (like GitHub Copilot, ChatGPT, or Devin) will automate parts of coding (boilerplate, debugging, docs) but can’t: 1 Understand complex business needs or ambiguous human requirements. 2 Design creative architectures or novel solutions. 3 Make ethical/critical decisions (e.g., privacy, security, trade-offs). Programming is more than writing code. It’s problem-solving, collaboration, and adapting to chaos—things AI struggles with. The “Junior Dev” Role Might Shrink AI can already: Generate simple code snippets. Fix common bugs. Answer Stack Overflow-style questions. Entry-level tasks may get automated, forcing new programmers to upskill faster (e.g., focus on system design, domain expertise). Future Programmers Will Look Different Shift from “writing code” to “orchestrating AI.” Example prompts: “Design a scalable API for X, optimize for cost, and explain trade-offs.” More emphasis on: Soft skills (stakeholder communication, UX empathy). Domain knowledge (healthcare, finance, etc.). AI-augmented workflows (prompt engineering, validation). Historical Parallels Fear: “High-level languages will kill coding!” → Instead, demand exploded. Fear: “No-code tools will replace devs!” → They just enabled non-devs. AI will likely create new roles we can’t yet imagine. Bottom Line Worst-case: Low-end coding jobs decline; programmers need to adapt. Best-case: AI removes grunt work, letting devs focus on harder, more meaningful problems. My advice: Learn to leverage AI, but double down on uniquely human skills (creativity, critical thinking, leadership). What’s your take? Excited or  ( 3 min )

Enable or Disable console.log Globally in JavaScript Sometimes, during development or debugging, you need to quickly enable or disable logging globally across your entire JavaScript application. Here's a straightforward approach to achieve this. console.log Before we override the console.log function, it's crucial to keep a reference to the original function. let original_console_log = console.log; This ensures you can restore the original functionality anytime you want. Next, create a function that can toggle logging on and off by replacing console.log. let logging_enabled = true; function set_logging(enabled) { logging_enabled = enabled; console.log = enabled ? original_console_log : function () {}; } Here's what's happening: When enabled is true, console.log points back t…  ( 4 min )

This includes: Pre-built service class Working demo UI Passing tests (mostly 😉) Step 2: The Magic Methods Convert Anywhere → UTC // Static call (no user context) $utcTime = UserTimeZoneHandler::toUtc( '2023-01-01 14:00', 'Asia/Tokyo' ); User-Friendly Instance Mode // In controller $handler = new UserTimeZoneHandler($user->timezone); // All conversions use the user’s zone $localTime = $handler->toUserTimeZone($event->start_time); Step 3: Avoid My Carbon Mistake I wasted hours on this failed test: public function testGoogleFormatting() { $time = Carbon::parse(...); // Fails! } Why? Laravel extends Carbon. Always use: use Illuminate\Support\Carbon; // Not Carbon\Carbon! Step 4: Add Your Secret Sauce New Calendar Provider? // Add to formatForProvider() 'zoom' => $utcTime->format('Ymd\THis\Z') Custom Time Ranges $converted = UserTimeZoneHandler::convertTimeRanges( $businessHours, 'America/Chicago', 'Europe/Paris' ); Step 5: Launch Your Demo php artisan serve Visit http://localhost:8000/timezone-converter to see: Why This Works ✅ Handles 597 timezones (including weird ones like Australia/Lord_Howe) ✅ Tests cover DST/edge cases ✅ No hidden dependencies Clone & Customize: github.com/codewithmikee/laravel-timezone-handler  ( 3 min )

Advanced Use Cases for Proxy in Data Validation Introduction to Proxy Introduced in ECMAScript 2015 (ES6), the Proxy object allows you to create a wrapper for another object, enabling you to define custom behavior for fundamental operations (like property lookup, assignment, enumeration, function invocation, etc.). This allows for considerable flexibility in handling objects. As applications grow in complexity, the need for robust validation strategies becomes vital—especially when dealing with data from various sources such as APIs, user input, or databases. While Proxy is often showcased with simple examples of intercepting property access, its true potential lies in advanced use cases such as data validation. Prior to Proxy, JavaScript relied on direct methods (such as co…  ( 6 min )

As we navigate through 2025, a significant paradigm shift is occurring in the AI landscape. While much attention has been focused on increasingly massive language models with hundreds of billions of parameters, a countercurrent has emerged: Small Language Models (SLMs). These lightweight yet powerful models are gaining tremendous traction among developers, enterprises, and researchers for their efficiency, practicality, and accessibility. SLMs, typically defined as models with fewer than 10 billion parameters (and often less than 1 billion), are proving that bigger isn't always better when it comes to solving real-world problems. Their rise represents a maturing of the AI field, moving from raw capability demonstrations toward optimized, targeted solutions. Small Language Models offer comp…  ( 7 min )

Em um cenário onde a agilidade deixou de ser diferencial para se tornar pré-requisito, ainda existem empresas que tratam infraestrutura como um custo fixo, estático, centralizado — e, muitas vezes, emocionalmente preso à stack de um único fornecedor. Essa escolha, além de técnica, é cultural. E, quase sempre, onerosa. Infrastructure as Code (IaC) não é sobre versionar configurações. A pergunta não é mais “por que usar IaC?” Quantas decisões financeiras, técnicas e operacionais sua empresa está deixando de tomar por não conseguir abstrair a própria infraestrutura? Porque enquanto sua equipe debate qual cloud é "melhor", a concorrência já está rodando workloads em múltiplos provedores, otimizando custo e latência em tempo real. Uma infraestrutura agnóstica não é luxo. É alavanca. Funções específicas com melhor suporte em outro ambiente? Roda lá. Região mais próxima do usuário? Você escolhe. Não é a cloud que decide. Quem domina a infraestrutura como código, domina o custo, o risco e a mudança. O problema não é a nuvem. Sem IaC, sua empresa não tem flexibilidade. Otimização não é uma planilha. É arquitetura. IaC não é sobre “como rodar melhor”. A infraestrutura deixou de ser suporte. E quem ainda não entendeu isso, vai continuar pagando caro por aquilo que deveria estar controlando.  ( 4 min )

There are a lot of design patterns, techniques, and ideas around us—both online and offline. An architect can always look towards them for inspiration. But it is very important to ignore the noise. In this series of articles, we will follow the book Righting Software by Juval Löwy, which refers to the entire concept of project and system design as "The Method". We will also refer to this idea as The Method throughout the series. By system design, we mean the design of the architecture, not the detailed design—which deals with how classes, interfaces, and contracts should be built within a component. Detailed design can be discussed in another series. There is a common misconception that a good architect needs decades of experience building systems to know what the right design decisions ar…  ( 5 min )

Over my 15+ years in web development, I've witnessed frameworks rise and fall, from jQuery to Angular, from Redux to React Query, and now to Remix.js.

When you’re building an app in ASP.NET Core, it’s easy to fall into the trap of just writing code that “works.” Especially when deadlines are tight. But if you’ve ever looked back at your project and thought, “Ugh, this is a mess,” then you know why architecture matters. Think of software architecture like the blueprint for a house. You wouldn’t build a house without planning where the walls, plumbing, and electrical systems go — same goes for your code. Here’s a common scenario I see all the time: Code Rot — where the codebase gets harder and harder to work with over time. The God Controller [HttpPost] public async Task Create([FromBody] OrderDto dto) { var order = new Order { CustomerId = dto.CustomerId, Total = dto.Total, CreatedAt = DateTime.UtcNow }; _context.Orders.Add(order); await _context.SaveChangesAsync(); return Ok(order.Id); } Looks simple enough, right? But think about what happens when you need: Good architecture gives you practical benefits: Yes, .NET is powerful. Yes, EF Core makes it easy to get started quickly. But most tutorials and templates push you toward patterns like: In this series, we’ll walk through real architectural patterns used in modern .NET applications — not just theory, but examples you can actually use in your next project. • Part 2: Layered Architecture – Classic, simple, and still useful. You don’t have to be at a huge company or working on a massive enterprise system to care about architecture. Even a small app can benefit from a bit of structure. If you're tired of messy codebases, hard-to-test logic, or struggling to add features without breaking things, this series is for you. Stick around — we'll turn those spaghetti controllers and thin services into something maintainable, scalable, and enjoyable to work with.  ( 5 min )

Originally published on Medium. Sharing what actually works (and what doesn’t) when using ChatGPT to plan real-world frontend features. When I start building a new feature, my biggest challenge isn’t the code — it’s deciding where to start. I used to open my editor with a vague idea like: “Build login page.” Ten minutes later, I’d have five tabs open, three half-written files, and no direction. Then I started using ChatGPT — not as a boss, but as a planning partner. Here’s how I use it to move faster without getting lost, and also where it sometimes fails. Instead of: “Build dashboard,” I ask: “Break down steps to build a responsive dashboard in Next.js.” It usually gives me: Set up layout Add sidebar, header Fetch data from backend Render UI components Handle empty/loading/error…  ( 4 min )

If you’ve been exploring AI or machine learning lately, you might have come across the terms embeddings and vector search. At first, they sound a bit technical, but they’re actually super cool and powerful ideas that help machines understand meaning — not just keywords. Imagine you want a computer to understand words, images, or even sounds. But computers don’t really get language the way we do. So what do we do? We turn these things into numbers. More specifically, embeddings convert data — like a word or a picture — into a list of numbers called a vector. These vectors live in a kind of “number space,” where the position of each vector captures the meaning of the original thing. Because items with similar meaning end up as vectors close to each other in this space. For example, the words…  ( 4 min )

Introduction The combination of React's component architecture with Tailwind CSS's utility-first approach has emerged as a compelling solution for modern web development. This integration addresses several pain points in traditional CSS methodologies while maintaining the flexibility needed for complex applications. Tailwind's utility classes work harmoniously with React's component model by keeping styles tightly coupled with their corresponding components. This eliminates the cognitive overhead of maintaining separate stylesheets and reduces the likelihood of styling conflicts in large applications. Tailwind's predefined design tokens (spacing scales, color palettes, typography settings) create consistency across React components without the need for custom CSS variables or style d…  ( 5 min )

go_router is one of the most popular package for managing navigation in a Flutter application, and since it became part of the Flutter team, it has become the main recommended solution. It's very easy to use, yet feature-rich. However, with the introduction of ShellRoute, observing the navigation flow in your app and having routes that are "aware" of navigation changes has become more difficult. As highlighted in this issue, when you add a ShellRoute, the app loses reactivity to route changes: the NavigationObserver is no longer triggered. While waiting for an official fix or built-in solution from the Flutter team, we can still implement route-aware behavior by listening to the GoRouterDelegate. The following code listens to the GoRouterDelegate throughout the widget's lifecycle and uses …  ( 4 min )

A few months ago, my manager assigned me to a project that required improving its search functionality. The team initially considered Elasticsearch as the primary solution, though they were open to exploring alternatives. I researched the topic and discovered PostgreSQL's full-text search. Since our data was already stored in PostgreSQL, I compared the two tools. The application I worked on served private users and had strict privacy regulations, with complex conditions determining who could view or edit specific data within the company. These intricate queries proved challenging for Elasticsearch to handle effectively, while PostgreSQL's full-text search, being built on top of SQL syntax, required no extra work to handle this. It also integrates seamlessly with our existing database, req…  ( 8 min )

Whether you’re debugging a stubborn production issue or architecting a scalable system, the nature of software development is deeply problem-solving at its core. Yet we rarely take a step back and ask: Are we solving problems effectively? Turns out, a Hungarian mathematician from the 20th century has some timeless advice for us. This post dives into some gold from George Pólya’s classic book, How to Solve It, and shows how its common-sense techniques originally meant for mathematics,are surprisingly useful for software engineers. Pólya's core idea is that general, common-sense questions help solve all kinds of problems,not just math ones. Consider these: What is the unknown? What are the data? What is the condition? These aren't math questions—they’re universal. They work whether you're …  ( 5 min )

Continuing on the topic of template engines, I would like to share my thoughts on the power of template engines, and how it relates to the power of abstractions in programming. First, let us look at the classification of template engines I have listed in my previous post: Logic-less: The template engine does not allow any logic in the template. All the logic is pre-applied to the variable content, our data, before it even arrives at the template engine. A typical example is Mustache. Logic-capable: The template engine allows you to define some logic in the template, such as not only what, but also when and how to display it. A typical example is Jinja2. Logic-full: Such template engines allow you to define any arbitrary logic in the template, by allowing you to even execute code in the …  ( 7 min )

1. Introduction In the technology sector, particularly in cloud computing like Amazon Web Services (AWS), two roles often come up: Solutions Architect and Presales. While both are critical in bridging technological solutions with customer needs, their responsibilities, skills, and work objectives differ significantly. This blog post focuses on clarifying the job descriptions and required professional skills for these two roles to provide individuals interested in pursuing a career in Cloud, but lacking clear career direction and undecided between these two positions, with a detailed and clear perspective. This will help them define their career goals. The article is not intended to diminish the value of either role.

I’ll keep this real — I’m a 21-year-old junior web developer from a small town in Gujarat, India. I never had the money to study Bachelor of IT or CS, so I taught myself how to code during my diploma in mechanical engineering. I have a huge passion for coding, After a few months of grinding through online tutorials, projects, and sleepless debugging nights, I landed my first dev job at a small service-based company. It doesn’t pay much (₹25k/month), but it was a start. I’ve been working on real projects using React, Next.js, etc., and learning more every day. Now the project I was working on just ended, and I have to return the laptop and PC the company gave me. I’ll still be working from the office on their machines, but I won’t have any personal setup at home. The problem is — that’s whe…  ( 4 min )

Dica de TI será uma série de posts com conteúdo sobre tecnologia. São posts curtos explicando alguns conceitos. Nos exemplos a linguagem usada será: Java Concatenar significa "colocar junto", “juntar-se”, “ligar-se” Para concatenar duas String, usa-se o método concat. Note que, já que o tamanho de uma String não pode mudar, a concatenação resulta na criação de um novo objeto. Também pode-se usar o operador + para a concatenação. Por exemplo, no trecho de código abaixo, a mesma linha é impressa duas vezes: String s1 = "Olá "; String s2 = "Mundo!"; System.out.println( s1.concat( s2 ) ); System.out.println( s1 + s2 ); As strings no java são imutáveis, ou seja, seu valor não muda A partir do java 15 tem um recurso chamado text blocks onde é possível formatar a string da forma como você quer que apareça, pode colocar parágrafo e espaço.

Written Date: 5/17/2025 For the last 2 years I've been using AI to drive most of my development efforts. It wasn't called "vibe coding" then, but it was just as frowned upon. The phrase "AI slop" was coined and tossed around willy nilly. Under every rock and around every corner you would find an expert ready to jump out and say that AI was overhyped. It was tenuous time to be using AI for helping you code. I will admit that the concerns brought forward were true then and are still mostly true now. However, there were these moments of brilliance that would shine through. These felt like samples of what was to come in the future, something that we would eventually consider to be just plain normal. I've held on to the inspiration and hope that came from those moments of clarity and brilliance…  ( 4 min )

Let's cut to the chase: Congressional Records are gold mines of political data, but they're trapped in PDFs and scattered across congress.gov. Yeah, there's an API, but it just gives you more PDFs or links to HTML pages. Not exactly AI-friendly. I needed plaintext, I needed it in bulk, and I needed it yesterday. So I built a Python tool that: Grabs data through the congress.gov API Ignores those pesky PDFs Extracts clean plaintext from the HTML pages Organizes everything neatly Why plaintext? Because you can actually do something with it! Search it, analyze it, feed it to AI models, cite specific sentences, or just read it without your eyes bleeding from PDF formatting. The tool leverages several key strategies to efficiently download records: The script uses the official congress.gov API,…  ( 6 min )

Alright, let's cut to the chase. You're building a React MVP. You need to be fast, lean, and focused on validating your core idea. So why, oh why, are you already thinking about t('user.welcome.message.short')? Internationalization (i18n) is crucial for global reach, no doubt. But for an MVP, traditional i18n setup is often a premature optimisation, a time sink when you should be shipping and iterating. It means wrestling with JSON files, getting lost with keys everywhere in your app, and losing velocity at a time you shouldn't. i18n-keyless This is where the "keyless" philosophy, then first time embodied by i18n-keyless, becomes your MVP's best friend. The concept is refreshingly simple: Just write your UI text directly in your components, in your main language. That's it. import * as I…  ( 5 min )

If you’re a web developer like me, you’ve probably styled a form before. And if you’re anything like me, you’ve tried to be helpful — maybe you added some color changes with input:valid or input:invalid, outlined fields, maybe even threw in a little transition effect. But then this came to your mind: Wait, why is this field showing up as valid before the user even typed anything? 🤦 Want smart web dev tips like this delivered straight to your inbox? join the newsletter and get your CSS selector cheat sheet for free You try to be nice to users. Give them visual cues. Maybe you change the border color on a valid input, or show a message when they make a mistake. You think you’re doing a good thing. But then someone opens your form and sees green borders before they’ve even clicked a thing. Valid already? They didn’t even type! It’s wrong. It feels broken. And worse: it actually is misleading. Let’s not even talk about accessibility. Using just colors for feedback? That’s a hard “no” if you care about users with color blindness. CSS pseudo-classes like :valid and :invalid don’t wait for the user to interact. If the input field meets the required rules on page load (or fails them), the styles apply instantly. That’s why your untouched email field might already look like a success story. Not cool. Say hello to :user-valid and :user-invalid. These two pseudo-classes work exactly how you always wanted :valid and :invalid to behave: *They wait for user interaction. Nothing changes until the user actually types, blurs, or otherwise engages with the input. Now that’s user-friendly feedback. If you’re still using :valid/:invalid on untouched fields, you're frustrating users. They’re seeing red borders before they’ve even typed anything. Or worse—green borders that falsely imply their input is good. By switching to :user-valid and :user-invalid, your forms become: ... Read the full article here  ( 4 min )

Problem 1 Longest Substring Without Repeating Characters Problem: You must write an algorithm that runs in O(n) time. Link to problem: https://leetcode.com/problems/longest-consecutive-sequence/description/ Approach: First Thought: Used a basic count[256] array to track frequency of characters. Tried checking frequency and updating start directly if a duplicate was found. Misplaced order of start++ and count[s[start]]--, which caused logic errors for overlapping characters. Final Approach: Used Sliding Window technique with two pointers start and end. Maintained a count array to track how many times a character appeared in the current window. On detecting a duplicate character (count[s[end]] > 1), shrunk the window using a while loop. Then decreased count[s[start]] and moved start forwar…  ( 5 min )

Introduction The Single Responsibility Principle (SRP) is the “S” in the SOLID principles of object-oriented design. It’s often mentioned, sometimes misunderstood, and rarely applied correctly in large Java applications. Definition: A class should have only one reason to change. In practice, this means a class should encapsulate a single, well-defined responsibility — not “one method” or “one functionality,” but one axis of change. In this article, we'll go beyond trivial examples and explore real-world SRP violations, how to spot them, and how to refactor for maintainability and testability. Consider the following UserService class: public class UserService { public void register(String email, String password) { if (!email.contains("@")) { throw new IllegalArgum…  ( 5 min )

By Alireza Minagar, MD, MBA, MS software engineer As a software engineer, I’ve spent most of my time making things work — efficient algorithms, robust logic, clean architecture. But recently, I gave equal attention to how software feels. Enter: SecureFleet, a desktop vehicle monitoring and management tool I’m building with Java Swing. At first, it was utilitarian — basic panels, a static table, and a couple of buttons. But I realized that professional software demands more than just working code — it deserves thoughtful, responsive, and intuitive interfaces. 🔨 What I’ve Implemented: A scrollable JTable with real-world vehicle tracking columns (Plate, Make, Model, Year, Owner, Status). A dedicated alert button (New Alert) highlighted in red for emphasis. A trio of functional buttons below: Track Vehicle, Add Entry, and Admin Panel. Clear color contrast and alignment for visual clarity. 🧠 What I Learned Along the Way: Grouping components into logical panels simplifies both alignment and code readability. GUI building tools (like NetBeans Designer) can help — but manual refinement makes the difference. 🌟 Why This Matters: 💡 What's Next: 🗣️ Let’s Talk: How do you balance aesthetics with functionality in desktop development?

Why I Switched from HashiCorp LRU to Ristretto for High-Performance Caching in Go While working on Buckt, I implemented a caching layer to speed up repeated file reads and downloads. I started with HashiCorp's lru, which was simple and easy to integrate. But as the system scaled and concurrency increased, it became clear that it couldn't keep up. This post highlights the issues I encountered and why Ristretto ended up being a much better fit. While the lru package is solid and predictable, I ran into a few limitations: Blocking Writes - All Add() operations lock the cache, leading to bottlenecks under concurrent load. Fixed Capacity, Not Cost-Based - It evicts based on item count, not memory usage — inefficient when storing large items like files. No Native Metrics - Hit/miss tracking mu…  ( 4 min )

We gradually transformed RxJS from an intriguing tool for experimentation into a powerful instrument for real-world tasks. Now, having taken three confident steps, it is time to confront the dark side of reactive programming. Like any technology, RxJS has its pitfalls. One of the most insidious is unclosed subscriptions, which can lead to severe issues such as memory leaks, performance degradation, and even app…  ( 10 min )

In the fast-growing fields of machine learning (ML) and artificial intelligence (AI), image annotation is fundamental to developing reliable models. That’s where image annotation comes in—the process of labeling and highlighting objects, features, patterns, or any other elements of an image that may be useful for a machine learning program or model. However, performing image annotation in-house can also be time-consuming, resource-intensive, and expensive. This is one of the reasons why outsourced image annotation has become a popular approach. In this post, we’ll examine the challenges of standalone image annotation and the best reasons to outsource image annotation for machine learning. 1.

In this video (an excerpt of our next Frontiers of Software Engineering interview), Genaina Rodrigues discusses the critical and evolving role of humans in autonomous and robotic systems, emphasizing the distinction between "Human in the loop" (where humans are directly involved in decision-making and can intervene) and "Human on the loop" (where humans supervise or monitor the system). She argues that humans are an inevitable part of these processes, whether as active or passive stakeholders. She uses several examples to illustrate her points, including challenges in autonomous driving and autonomous avionics. A significant portion of her discussion focuses on the Boeing 737 MAX crashes. She explains that the accident wasn't just a system failure but involved a cascade of issues, includin…  ( 3 min )

Handling async errors in JavaScript often turns into a mess of try-catch blocks everywhere. It clutters your code and gets harder to deal with as the project grows.

The Java if-else-if ladder is a fundamental control flow statement widely used in programming to make multiple decisions based on different conditions. It allows developers to execute specific blocks of code depending on which condition evaluates to true, providing a clean and efficient way to handle complex decision-making scenarios. This construct is essential for writing robust Java applications, especially in areas like software development, web applications, and backend services. In practice, the if-else-if ladder helps streamline conditional logic by checking one condition after another until one matches. This approach reduces nested code complexity and improves readability, which is crucial for scalable and maintainable code. It’s often paired with other control structures and modern Java features to optimize performance and user experience in real-time applications.  ( 2 min )

Welcome, my fellow denizens of the cyber realm. If you've ever dared to manipulate a Python list like some medieval peasant, let me introduce you to a tool so blazingly efficient that it makes lists look like dial-up in a fiber-optic world: Queues. We’re running a little duel here—Python’s list.pop(0) versus deque.popleft(). The former? Laughable. It’s the floppy disk of data structures—archaic, slow, and embarrassing in modern computing. Meanwhile, deque? It’s the neural uplink to pure speed. Here’s the showdown: import timeit from collections import deque def list_pop(): lst = list(range(10**5)) while lst: lst.pop(0) def deque_popleft(): dqe = deque(range(10**5)) while dqe: dqe.popleft() if __name__ == '__main__': list_time = timeit.timeit(list_pop, number=1) deque_time = timeit.timeit(deque_popleft, number=1) print(f"List.pop(0) time: {list_time:.6f} seconds") print(f"Deque.popleft() time: {deque_time:.6f} seconds") Operation Execution Time List.pop(0) 1.218925 sec Deque.popleft() 0.006576 sec Read that again. Lists are basically waiting for the apocalypse while queues are flying first class to the future. The list operation is O(n)—which means each time you pop an element, the entire list gets shuffled like some analog relic. Deque, on the other hand, is O(1)—swift, seamless, untouchable. If you’re still using lists where queues would suffice, you’re practically inviting disaster. Imagine hacking the government’s mainframe with code so inefficient it takes a millennium to execute—no, thank you. Upgrade to deque, ascend beyond mortal constraints, and let your programs breathe the sweet air of efficiency. This has been Warlock's Data Structure Command Center—stay frosty out there.  ( 3 min )

⚙️ Why Optimize React Apps? 🧠 The Problem In traditional React setups, all JavaScript code is bundled (using tools like Vite or Webpack) into a few files, often a single large main.js or bundle.js. On initial page load, the browser must download, parse, and execute this entire bundle before the application becomes interactive. Larger applications lead to larger bundles → slower Time-to-Interactive (TTI) and worse Largest Contentful Paint (LCP). Impact: Slower apps cause user frustration, higher bounce rates, and potentially worse SEO. Significantly reduce the initial JavaScript payload. Improve Time-to-Interactive (TTI), making the app usable faster. Enhance perceived performance and overall user experience, particularly on mobile and slow network connections.

Let me get straight to it, I used to transfer data from Files.com or any other platform where files were dropped to our cloud buckets using scripts. It was all okay when the file sizes were within a few MBs, but things got painful once they grew into GBs. It started taking a lot more time. To speed things up, I tried running the transfer on a VM, it did get faster, but not faster faster, especially when the size crossed 400+ GB. That’s when I started looking for a better way to connect my GCP/AWS buckets directly with these storage platforms, something that could make the transfer process faster and more reliable.

Good error reporting is crucial in programming languages. Doing it at compile time was easy in ArkScript as we have all the context we need at hand, but since we compile code down to bytecode, which is then run by the virtual machine, we loose a lot of context: the source files, their path, their content, we don't have that anymore! Our runtime errors could only show the VM internal state. This article is about how it all changed. I went to the drawing board, and three solutions presented themselves to me: create a source location table in the bytecode, mapping an instruction to a file and line ; emit special instructions that would be skipped by the VM, and used only when the VM crashed, backtracking to find the nearest SOURCE instruction ; extend the size of instructions to 8 bytes and u…  ( 6 min )

Bag of Words (BoW) is a foundational technique in text processing, where text is transformed into numerical vectors based on word presence and frequency. It is a simple yet powerful method for converting text data into a format that machine learning models can understand. Why the Name "Bag of Words"? The term "Bag of Words" comes from the idea that the model treats text like a "bag" of words: It only cares about the presence of words (do they exist?) and their frequency (how often they appear).

Psicologia das decisões, arquitetura da informação e dark patterns. Quando você clica em um botão, desliza um controle ou preenche um formulário… Você realmente escolheu fazer aquilo? Ou a interface já havia decidido por você, através de posicionamento, cor, linguagem ou contexto? Sistema 1: Rápido, automático, inconsciente. Usa heurísticas, hábitos e emoções. Sistema 2: Lento, consciente, deliberado. Usa lógica e análise. Designs eficazes interagem majoritariamente com o Sistema 1, que é preguiçoso e busca atalhos. Isso faz com que pequenas decisões visuais tenham enorme influência sobre nossas ações. O layout, cores, texto e ordem dos elementos não são neutros.

Dear Dev Community, Between classes, late-night coding, and the occasional existential crisis, I realized something: school can be overwhelming. There’s always a deadline, always a distraction, and platforms like WhatsApp or Telegram—while useful—aren’t really designed for focused learning. So instead of just complaining about it, I decided to build something. 🎓 Meet Rucks. 🧠 The Problem I wanted something that understood student life. So I built it. ✨ What is Rucks? Plan their days and assignments Track learning goals Reflect and improve Stay motivated without social media noise It’s simple, focused, and built around real academic pain points. It also integrates MxAnalytica, a small analytics engine I built to help improve the experience based on real usage—not assumptions. 🔧 Tech Stack Backend: Dart Frog + Drift for lightweight local storage Analytics: MxAnalytica (custom engine) No Google services — I wanted to build something privacy-respecting and independent 📦 Why I Built It This Way "Between classes, coffee sips, and the occasional existential crisis." Every design choice was guided by real needs and actual friction points I (and my peers) experience as students. 🔍 What’s Next? I'm also exploring ways to monetize it without compromising the experience. If you’ve built something similar or have thoughts on that, I’d love to hear from you. 🧑‍💻 Call for Feedback & Collab Got ideas? Want to test it out?

Successfully hosted a static portfolio using S3 + CodePipeline, documented the entire flow, fixed initial errors, and gained hands-on AWS experience. "Show your portfolio using S3 and CodePipeline." That's what the interviewer said. And guess what I did? I half-did it — only used S3, completely forgot about CodePipeline. Classic fresher moment. But I didn’t stop there. After some caffeine, chaos, and clicking around AWS documentation like a lost tourist, I figured it out! Hosted my portfolio on Amazon S3 deployment using AWS CodePipeline(if you change in index.html it will sudden showcase)--i think automated i don't know I’ve documented every step and every mistake (yes, including naming my bucket static-website-hosting-swiggy because... panic mode ). Lessons learned: Don’t rush. AWS has enough buttons to confuse the calmest soul. Automate with CodePipeline — it’s not just for big apps.

What is a parallel public chain? The transaction execution of traditional smart contract platforms (such as Ethereum) is serial: one transaction can be executed only after the next one is executed, and even if the transactions do not affect each other, they cannot be processed in parallel. This leads to a very low throughput (TPS). Ethereum has an average of only a dozen TPS, and transaction congestion and gas fees soar during peak hours. Parallel public chains are different. They analyze the dependencies between each transaction and execute independent transactions on multiple computing cores at the same time. In layman’s terms, it is to make the blockchain multi-channel parallel operation like an assembly line, split the tasks into small pieces and process them in parallel, which can gre…  ( 6 min )

This turned out to be a pretty cool concept. While working on my site monitoring app, I had around three or four services like uptime checks, DNS lookups, pinging, and a few others. Since I’m not much of a UI designer, I ended up creating separate files for each service, even though they all shared the same layout. That’s when I discovered Flask’s template inheritance. Instead of repeating the same code over and over, you can create a base layout and reuse it wherever you want. It really helped clean things up and made everything way easier to manage. Here’s how you can set it up. template-inheritance home about contact Then, in your child template, you extend the base and override that block: {% extends "base.html" %} {% block content %} hello world!! {% endblock %} That way, you get the shared layout and can customize parts of the page without repeating your code.  ( 3 min )

🚀 What Are Generics in TypeScript? When developing applications, we often need flexibility while maintaining type safety. TypeScript’s Generics solve this challenge by allowing us to create reusable components that can work with multiple data types. In this guide, we’ll break down generics step by step, ensuring you fully understand how to use them efficiently. Without generics, you would need separate functions for different data types. For example: function returnString(value: string): string { return value; } function returnNumber(value: number): number { return value; } This approach leads to redundant code. Generics solve this problem by creating a single function that works for all types. Generics use a placeholder type, such as , allowing a function to handle various dat…  ( 5 min )

Article originally published here : https://alsohelp.com/blog/how-to-display-git-shortsha-in-terminal I had a problem displaying the image here on dev.to, everywhere else, the text is fine Article below : The answer is already given in this StackOverflow answer more than 6 years ago (!) and still holds true nowadays : git rev-parse --short HEAD # 4d7b213 In Git every commit is identified by a 40-character hexadecimal string named the "Git SHA". See the commit number pointer by the arrow ? (view it in original article) Yes, that's the git short SHA. Only the first 7 digits amongst the 40. The risk of collision is small enough to identify uniquely each commit. You can define an alias, on Linux or Windows, in order to display it without to remember the whole command : alias shortsha='git rev-parse --short HEAD' (exemple from my Linux machine) Will be used like this : shortsha # 4d7b213 Neat! Sometimes, you will try some attempt to display it somewhere in the footer, in order to increase confidence about which version of the website is deployed. I like and use it, but I admit it's not very common though. That was a quick recap about the git short SHA.  ( 3 min )

Leapcell: The Best of Serverless Web Hosting Node.js combined with Express.js remains a golden combination for building efficient web applications. When we need to provide dynamic HTML content to the client, Express introduces the concept of a "view engine". Over the years, EJS (Embedded JavaScript) has become a popular choice due to its simplicity. However, since the advent of React, JSX (JavaScript XML), with its component-based UI construction approach, has gained enormous favor among developers, and its philosophy is also fully applicable to server-side rendering. This article will delve into how to use traditional EJS and modern JSX to implement server-side rendering (SSR) in an Express.js application developed with TypeScript.

How High-Performing Dev Teams Use Async Communication to Stay Productive Pratham naik for Teamcamp ・ May 17 #webdev #productivity #devops #opensource  ( 2 min )

Introduction In the fast-paced world of software development, every line of code counts—and so does every minute of your day. As tech teams increasingly embrace remote and hybrid models, we must clearly rethink how we communicate. Daily stand-ups, endless Zoom calls, and constant Slack notifications are no longer the productivity boosters they once seemed to be. Instead, high-performing developer teams use asynchronous (async) communication to stay aligned, reduce interruptions, and get more done. Daily stand-ups were designed to be quick, focused meetings to keep teams in sync. But in reality, they often: Happen at inconvenient times across time zones Turn into lengthy status updates Break developer flow and deep work Add unnecessary meeting fatigue According to a recent GitLab Remot…  ( 5 min )

Well, I want to say something here before moving forward. I had no idea people would read my first post, especially since it was my first time writing an article.

Adding scroll-based animations to your website used to mean reaching for JavaScript — from scroll event listeners to Intersection Observers or third-party libraries like ScrollMagic or GSAP. But what if you could get the same effect with just pure CSS? Meet the modern magic of CSS: animation-timeline: view(); With this property, you can create scroll-triggered animations without a single line of JavaScript. Smooth. Performant. Declarative. ⸻ 🧠 What Is animation-timeline: view();? The animation-timeline property allows CSS animations to be driven by something other than time. When you use the special value view(), the animation is controlled by the element’s scroll position in the viewport. That means your animation will start and progress based on how far the user has scrolled…  ( 4 min )

If you’re using Cursor and keep seeing this error: “Connection failed. If the problem persists, please check your internet connection or VPN” You’re not alone. This issue tends to appear randomly—even when your internet is working just fine. It can interrupt your flow and make the experience frustratingly unstable. Cursor uses the HTTP/2 protocol to power many of its AI features, since it allows streaming responses. However, not all networks handle HTTP/2 properly. If you're on a corporate network, using a VPN, or behind a proxy like Zscaler, HTTP/2 connections might fail. As a result, Cursor may struggle to index your code or connect to its AI backend—leading to that annoying “Connection failed” message. Thankfully, there’s a simple workaround. Cursor now includes a fallback to HTTP/1.1, which is slower but much more reliable on certain networks. Here’s how to enable it: Open Cursor Settings (Cmd or Ctrl + ,) Go to VS Code Settings Search for http2 Find and check the option “Disable HTTP/2” This forces Cursor to use HTTP/1.1 instead, which should fix the connection issue and restore access to AI features. ✅ Once you do this, the error should stop showing up and things will run more smoothly.

Amazon Sellers: Navigating the Tariff Disruption Landed costs on China-sourced SKUs have surged by 30–50%, compressing already razor-thin contribution margins. Raise prices, and you lose to the competition and tank conversion. Hold prices, and you bleed cash on every sale. Inventory caught mid-transit racks up storage fees at 3PLs. New suppliers from Vietnam, Mexico, or the U.S. bring delays, compliance challenges, and no keyword history — right when your ad budget is already stretched thin.

Understanding the Basics of Machine Learning with Python Machine learning (ML) is revolutionizing industries, from healthcare to finance, by enabling computers to learn from data and make intelligent decisions. If you're new to this field, Python is the perfect language to start with due to its simplicity and powerful libraries. In this guide, we'll break down the fundamentals of machine learning, explore key concepts, and provide practical Python examples to get you started. What is Machine Learning? Machine learning is a subset of artificial intelligence (AI) that focuses on building systems capable of learning from data without explicit programming. Instead of writing rigid rules, ML algorithms identify patterns and make predictions or decisions based on input data. There are three main…  ( 4 min )

If you're using an SSD — and let’s be honest, you probably are — you might have come across a spec labeled TBW, or Terabytes Written. But what does it actually mean for the real-world lifespan of your drive? Let’s break it down in simple terms. TBW stands for Terabytes Written, and it’s a metric that tells you how much data can be written to an SSD before the drive is likely to start wearing out. Think of it like a fuel limit — not for how long the drive will exist, but for how much write work it can handle over its lifetime. For example, if your SSD has a TBW of 600, that means you can write 600 terabytes of data to it before you start entering the "wear-out" zone, as defined by the manufacturer. Let’s do a quick, real-world calculation. Say you're a regular user writing about 100 GB per day — downloading files, installing apps, updating your system, working on projects. That’s quite a bit for a typical user, but let’s go with it. 100 GB/day = 36.5 TB/year 600 TBW / 36.5 TB/year ≈ 16 years Yes, sixteen years of daily 100GB writing. That’s how much endurance a 600TBW SSD gives you. And if you write less than that (which most people do), it’ll last even longer. You can monitor your SSD’s health and total data written using tools like: CrystalDiskInfo (Windows) smartctl from smartmontools (Linux/macOS) These tools can show you how much data has been written so far, so you can get a real-time sense of your drive’s life expectancy. TBW is an important but often misunderstood metric. SSDs don’t just suddenly die after hitting the limit, but the risk of data loss increases as the flash memory wears out. That said, for most users — even power users — modern SSDs offer years of reliable performance. So the next time you see a TBW rating, don’t panic. Unless you're stress-testing your drive daily, you're probably fine for a decade or more.  ( 3 min )

In a world overflowing with digital tools, it’s easy to dismiss mental math as outdated — a quaint relic from the pre-calculator age. But there’s something uniquely powerful about sharpening your ability to think numerically without external support.

The Portable Document Format (PDF), formalized as ISO 32000, has been the global workhorse for digital documents since the 1990s. It was a revolutionary answer to the chaos of inconsistent document rendering across platforms, ensuring that every reader would see the same layout, regardless of software or hardware. From government agencies and hospitals to enterprise back offices and freelance contracts, PDF has become a trusted container of visual fidelity and permanence. But here’s the challenge: the modern digital world doesn’t run on permanence alone. It runs on interactivity, data-driven workflows, responsive design, and seamless integration.

And then they switch from having to be massive consumers of data to extremely massive broadcasters of data. So that means that they need huge amounts of resources both on ingress an…

Moody's credit rating agency downgraded the credit rating of the United States government from Aaa to Aa1, citing the rising national debt as the primary driver behind the reduction in creditworthiness. According to the May 16 announcement from the rating agency, US lawmakers have failed to stem annual deficits or reduce spending over the years, leading to a growing national debt. The rating agency wrote: "We do not believe that material multi-year reductions in mandatory spending and deficits will result from the current fiscal proposals under consideration. Over the next decade, we expect larger deficits as entitlement spending rises while government revenue remains broadly flat." The credit downgrade is only one degree out of the 21-notch rating scale used by the company to assess the c…

South Africa’s Garden Route, famed for its lush forests, expansive beaches and charming towns, has become a testbed for Bitcoin adoption. From Mossel Bay to Witsand and Plettenberg Bay to Knysna, Bitcoin has become popular among shop owners and travelers alike for a multitude of reasons. “We’re seeing the early signs of a parallel, permissionless economy emerging across an entire region,” James Caw, founder of SimplB — a local crypto asset provider — told Cointelegraph, “where small businesses benefit from faster, lower-cost digital payments and where people have more options to earn, send and receive sound money securely.” For tourists, the benefits are immediate: no currency exchange hassles, no international card fees, and the ability to pay instantly and securely. For locals, Bitcoin (…

Opinion by: Merlin Egalite, co-founder at Morpho Labs Fintechs in the front, decentralized finance (DeFi) in the back: the DeFi Mullet. Today’s fintech companies offer excellent user experiences but are constrained by traditional financial infrastructure — siloed, slow, expensive and inflexible. Meanwhile, DeFi provides lightning-fast, cost-effective, interoperable infrastructure but lacks mainstream accessibility. The solution? Combine fintech’s distribution and user experience with DeFi’s efficient back end. The mullet is inevitable Fintech companies heavily rely on traditional financial (TradFi) infrastructure that is siloed, slow to deploy and run, and costly to maintain. This inefficiency limits their control over costs and product offerings and has potential infrastructure risks. Fin…

Bitcoin’s next explosive move could send the asset to $250,000 by the end of 2025, according to Scott Melker, a crypto analyst and host of The Wolf of All Streets podcast. Speaking in a recent interview, Melker cited growing institutional interest and diminishing volatility as key factors that could drive the next leg up. “250K this year, totally possible,” Melker said, adding that Bitcoin (BTC)’s volatility has declined significantly in recent years. “It used to be about three times as volatile as the S&P. Now it’s less than two times.” He pointed to increased involvement from pension funds and ETF issuers as evidence of a more mature, stable market. The shift, he argued, reflects a broader trend of institutional adoption. “The more institutional money, the more Wall Street money, the mor…

The US Securities and Exchange Commission (SEC) has held discussions with Everstake, one of the largest non-custodial staking providers globally, to explore clearer regulatory definitions around staking in blockchain networks. The meeting, which also involved the SEC’s Crypto Task Force, comes at a time when over $193 billion in digital assets are staked across major proof-of-stake (PoS) networks. However, despite the massive scale of participation, staking remains in a legal gray zone in the US as regulators wrestle with its classification under existing securities law. The previous SEC administration also took enforcement actions against major players such as Kraken, Coinbase, and Consensys due to their staking services. The agency, under pro-crypto President Donald Trump, has recently d…

A man from Wellington, the capital city of New Zealand, has been arrested in connection with an FBI-led investigation into a global cryptocurrency fraud operation that allegedly stole $450 million New Zealand dollars ($265 million). According to New Zealand Police, the man is one of 13 individuals charged after authorities executed search warrants across Auckland, Wellington, and California over the past three days. The charges stem from allegations that members of an organized criminal group manipulated seven victims to obtain large amounts of cryptocurrency, which was then laundered through multiple platforms between March and August 2024. The US Department of Justice has indicted the man under federal law, including charges of racketeering, conspiracy to commit wire fraud, and conspirac…

Panama City Mayor Mayer Mizrachi has hinted at establishing a city-level Bitcoin reserve in a cryptic post following his meeting with two of El Salvador’s Bitcoin policy leaders. “Bitcoin Reserve,” Mizrachi wrote to X on May 16 after meeting El Salvador-based Bitcoiners Max Keiser and Stacy Herbert. While Mizrachi didn’t share details about his discussions with Keiser and Herbert, the timing of the post came 11 days before the Bitcoin 2025 conference in Las Vegas, where Mizrachi is scheduled to speak.

Paraguayan law enforcement has deported three individuals and arrested another for attempting to steal crypto miners at a facility near the country’s Itaipu hydroelectric dam. According to a May 15 statement from Paraguayan prosecutor Irene Rolón, the men were caught by police soon after breaking into a locked section of Teratech SA’s facility in Coronel Bogado, leading to their arrest. Prosecutors believe the men may have had ties to Teratech as independent contractors, but are still waiting on official confirmation from the company’s CEO. The three deported were Chinese nationals Jinping Duan, Tian Jianyun and Zheng Guanglong, who did not have official entry records into the country. Paraguayan authorities and Interpol believe the men illegally entered through Brazil or Bolivia. The thre…

Key takeaways: Traders expect a Bitcoin price pullback to $90,000, but a bull flag could break out to new highs if profit taking near the range highs reduces. On-chain data suggests the current profit taking is too weak to extinguish Bitcoin’s current price momentum. Bitcoin (BTC) price has spent the bulk of the week pinned below $104,000 to $105,000, which many analysts have labelled as a resistance zone, but an alternative view suggests that BTC is simply consolidating within a bull flag. A bull flag is a continuation pattern that is characterized by a period of sideways price action following a sharp uptrend, and when the structure confirms or breaks from the trendline resistance, the uptrend continues.  BTC/USDT 1-day chart.

Engineering is more than formulas, projects, or classroom lectures. While academic learning builds a foundation, real-world experience shapes your mindset, communication, and decision-making abilities. From my own journey, I’ve seen how industrial training, leadership roles, and volunteering helped me grow far beyond the textbook. When you work in a real production environment, like a garment factory, you begin to understand how things actually work on the floor. Industrial training teaches you about time management, coordination, and how teams solve problems in real-time. You observe how small improvements in workflow or communication can bring large results. This kind of learning is something no classroom can fully teach. Leadership roles in university also help in developing essential soft skills. Organizing events, managing volunteers, and communicating under pressure make you more confident and responsible. It teaches you how to plan, lead, and adapt — which are valuable qualities in both academic and professional life. Volunteering adds another layer to your development. It allows you to give back to your community while also learning empathy, teamwork, and people skills. Volunteering shows that you are proactive and socially responsible, which employers and organizations appreciate. These experiences make your resume stronger, but more importantly, they shape your personality. They prepare you for interviews, teamwork, and real challenges in your career. You learn how to think practically, solve problems, and communicate your ideas clearly — all of which are essential in today’s job market. If you are an engineering student, try to step outside your comfort zone. Look for internships, attend workshops, join a leadership program, or take part in a volunteering activity. The real world is the best teacher, and the lessons you learn there will stay with you forever. Start early, stay curious, and take every opportunity to grow.  ( 3 min )

Go language provides two commonly used ways to allocate memory: make and new. Although both are used for memory allocation, their roles and usage scenarios are quite different.

We didn’t set out to build a typical database. We built something that works with the Postgres you already use, scales when you need it, and doesn’t require throwing everything out just to keep growing. This is a golden age for databases. There’s distributed systems, cloud-native options, fully managed services, and battle-tested engines like Postgres that keep getting better every year. But despite all that progress, scaling your database is still surprisingly hard. Many teams still build applications with a single-node Postgres backend. It’s how a ton of apps start, and how they stay for as long as possible. And for good reason. Postgres is rock solid, well-loved, and everywhere. It’s mature, feature-rich, and backed by an incredibly active community. But fast forward a bit, and that sin…  ( 4 min )

She explained her smartphone was an older model, using Android 8.0, aka Oreo, and that's probably why the chatgpt android app wasn't downloading and installing on it. We talked a while, and I pondered that while there are a lot of reasons for an app not to work on an older Android OS version, the most relevant of them are the security reasons.

Hello, everybody! At Info-Polus, we see the opportunities RWA tokenization presents. Today, let's dive into it! The crypto bull market is not only driving up the large, established cryptocurrencies such as Bitcoin and Ethereum. Memecoins such as Dogecoin (DOGE), Pepe, and Shiba Inu, which have a lower market capitalization and are particularly volatile, have recently attracted great attention with impressive price rallies. By contrast, the increases in real world assets (RWA) have attracted less public attention - although many experts believe this crypto segment has excellent prospects… So what lies in RWA? As the name itself suggests, Real World Assets represent tangible and other assets existing in the “real world” (real estate, exchange-traded commodities, art objects) tokenized for use in the DeFi segment. The growing interest in tokenizing real-world assets stems from the promise of greater transparency, security, and global market reach. Let the numbers speak for themselves: the DeFi industry has boomed over the past few years, peaking at $181.22 billion in total value locked (TVL) on December 2, 2021. According to DefiLlama, RWA is steadily carving out its space in this ecosystem, with a TVL exceeding $8 billion in January 2025. Interested in what the future of RWA holds for us?

During my industrial training, I had the opportunity to explore Lean Manufacturing, a system designed to make production more efficient by eliminating waste and focusing on value creation. I learned about important tools like 5S, which stands for Sort, Set in order, Shine, Standardize, and Sustain. This method helps keep workspaces clean and organized, which is essential for safety and productivity. Another key concept I studied was Kaizen, which means continuous improvement. It emphasizes that small daily changes can lead to significant improvements over time. I also gained practical experience with Just-in-Time inventory management, which ensures materials arrive exactly when needed, reducing storage costs and avoiding overproduction. This training helped me connect the theoretical concepts learned in class with real-world production challenges. I realized that efficiency is not only about speed but also about smart use of resources and people. I saw how teamwork and communication play a vital role on the factory floor. Lean Manufacturing is not just a set of techniques; it is a culture of continuous problem solving and improvement. As an Industrial and Production Engineering graduate, I believe this mindset will guide me in all my future professional endeavors.  ( 3 min )

Oreo is a black and white male cat who spends his days judging my code from the comfort of my desk chair (which he has claimed as his throne). Like most cats, he believes he owns everything - a perfect metaphor for understanding JavaScript's various scoping mechanisms! Let's start with regular class variables and methods. Oreo's name and color are regular properties - anyone can access them. class Cat { constructor(name, color) { this.name = name; this.color = color; } meow() { console.log(`${this.name} says: Meow!`); } } const oreo = new Cat("Oreo", "Black & White"); oreo.meow(); // Oreo says: Meow! console.log(oreo.color); // Black & White - We can access and modify this property Static variables and methods belong to the class itself, not instances of the class.

Obsidian has become a go-to tool for developers, researchers, and writers who want to manage their knowledge in a flexible, local-first way. With Markdown-based storage, plugin extensibility, and full control over your data, it offers an ideal environment for serious note-taking and knowledge work. As large language models (LLMs) have rapidly improved, many of us have started integrating AI into our workflows — for summarization, idea expansion, information retrieval, or even querying our own notes. Tools like ChatGPT, Notion AI, or Obsidian GPT plugins offer these capabilities, but they often come with strings attached: You need an API key (usually OpenAI) Your notes are sent to a third-party cloud You have no control over how models behave Offline usage is unsupported or limited That was…  ( 8 min )

Hey folks, welcome! Welcome to the first article in my new series: Why Python? Unlike C, Python is widely used—and one big reason is libraries. Python comes with many built-in libraries, and you can import even more depending on what you need. Think of a library as a toolkit that helps you do things faster and easier. A Real-Life Example: Randomness Let’s say I’m playing a card game with friends. I never know which card I’ll get next—why? Because it’s shuffled. It’s random! In Python, we can use something similar: import random as rand Just like shuffling cards gives you unpredictable results, the random library in Python helps you generate random numbers or make random choices. In real life, randomness is unpredictable. Cool, right? That’s the magic of Python! Introduction to Variables Now let’s talk about variables. Imagine a kitchen shelf with jars: In programming, think of those jars as variables. Each jar (or variable) stores something inside it—just like a variable stores data. Syntax Example: Let’s say we name our jars like this in Python: jar1 = "Sugar" Now, if we want to see what’s inside, we can do: Easy, right? That’s a wrap! In the next article, we’ll look at types of variables and best practices for naming them. Happy coding! If you found this interesting or have suggestions, feel free to comment — I’d love your feedback!  ( 3 min )

2901. Longest Unequal Adjacent Groups Subsequence II Difficulty: Medium Topics: Array, String, Dynamic Programming You are given a string array words, and an array groups, both arrays having length n. The hamming distance between two strings of equal length is the number of positions at which the corresponding characters are different. You need to select the longest subsequence1 from an array of indices [0, 1, ..., n - 1], such that for the subsequence denoted as [i0, i1, ..., ik-1] having length k, the following holds: For adjacent indices in the subsequence, their corresponding groups are unequal, i.e., groups[ij] != groups[ij+1], for each j where 0 < j + 1 < k. words[ij] and words[ij+1] are equal in length, and the hamming distance between them is 1, where 0 < j + 1 < k, for all indices…  ( 26 min )

It’s been a long time coming, but I’m thrilled to finally share a new developer tool that emerged from my constant need for better CSS property organisation: Old Fashioned CSS Formatter — a professional-grade Visual Studio Code extension designed to fill a very real and long-standing gap in modern front-end development. If you’ve ever used CSSComb in the past, you know how much it helped maintain order in stylesheets. However, a vacuum was left with the project, which is no longer maintained, and this new tool steps in. When CSSComb stopped receiving updates, it left a hole for many developers, including me. It had a simple job: sorting CSS properties meaningfully. But it did it well. With tools like Stylelint and Prettier becoming more prevalent, it seemed like no one focused anymore on …  ( 4 min )

This is the fourth chapter in my blog series about building a Go Testing Module from scratch. If you’re new here, I recommend checking out the previous post for some context. In this post, I’m diving into two new packages I’ve created — goldy and must. These tools tackle problems you’ve probably faced in writing tests, making your test code cleaner, more readable, and a lot more enjoyable to work with. Let me walk you through how I built these packages to solve those familiar testing headaches. goldy Package You’ve likely faced the frustration of testing a function that generates a complex, multi-line string — like a JSON response or a formatted report.

This post demonstrates a TypeScript pattern I've been experimenting with for the last year or so. I've been calling this pattern "inductive type constraints", but perhaps a better name would be "smart constructors", since they have "correct by construction" semantics (here's a nice article about them). "Smart constructors" definitely sounds cooler, but "inductive types" are what they're called in other typed languages, so I went with that. Before we dig into how they work, here are a few examples of how they can be used to solve a few long-standing TypeScript issues: Exact "exact types" is the 2nd-most popular feature request of all time Exact ensures that a type does not have any extra properties (Playground) Json One of the oldest TypeScript issues (#187) (Playground) In the TypeSc…  ( 4 min )

A Python package named modinit that facilitates the rapid scaffolding of AI model training repositories with a standardized, best-practice structure. This tool is designed to save time and ensure consistency across machine learning projects.

Calculus is often taught as a tool for solving problems, such as rates of change, areas under curves, and optimization. But what if it’s also a lens to understand how the world quietly evolves? In coding, every function, loop, and variable tells a story about change—about moving from one state to another, sometimes subtly, sometimes dramatically. The derivative isn’t just a slope; it’s a whisper about the next moment. The integral isn’t just an area; it’s the sum of all moments passed. As a developer and math lover, I find myself drawn to these silent narratives, where math and code meet philosophy. In this space, I’ll explore those intersections: How math powers AI models How quantum ideas challenge our intuitions How elegant code can be more than just efficient — it can be poetic. If you love thinking deeply about the things most take for granted, welcome aboard. Let’s decode change together!!  ( 3 min )

Have you ever wondered how Node.js handles asynchronous operations so efficiently? The secret lies in the Event Loop, a core component that orchestrates the execution of tasks. In this series, "Node.js Event Loop Visualized," we will dive deep into the inner workings of the Event Loop using a powerful tool: the Event Loop Visualizer. The Event Loop Visualizer is a tool I've been developing, based on a fork of an existing project. It offers a unique insight into the real execution of the Event Loop by utilizing a modified version of the Node.js core. Unlike other tutorials, courses, and posts that often rely on simulations to explain the Event Loop, this tool captures the actual execution, recording each phase in real-time. This provides a clearer and more accurate understanding of how Node.js manages tasks and events. Feel free to explore the Event Loop Visualizer and see it in action for yourself! The Event Loop Visualizer is composed of several key sections: Code Editor: Write and execute JavaScript code to see how it interacts with the Event Loop. Macrotask and Microtask Queues: Visualize how tasks are queued and processed. Call Stack: Observe the current call stack and how functions are executed. Event Loop Phases: Track the different phases of the Event Loop, such as Timers, Poll, and Check. Ticks & Rejections Loop Phases: Understand how Node.js handles next ticks and microtasks. Metrics: Monitor loop counts and event processing statistics. Simulated Terminal: View real-time output from your code execution. In each post of this series, we will analyze a specific block of code and explore how it is executed within the Event Loop. We'll cover a range of examples, from basic like timers to more advanced such as handling sockets and streams. Stay tuned as we embark on this journey to demystify the Node.js Event Loop. Whether you're a seasoned developer or just starting, this series will provide valuable insights and practical knowledge. Let's get started!  ( 3 min )

This document provides a step-by-step guide for integrating GitHub Actions to automate the restoration of a production AWS RDS PostgreSQL database for use in development environments. EKS cluster. Postgres database (I am using AWS RDS in this example.) Github Repository. AWS IAM service. AWS S3 bucket. We have an Amazon RDS cluster running a PostgreSQL database, referred to as gerx_db_prod. Additionally, there are several lower-tier environments—such as gerx_db_dev_1, gerx_db_dev_2, and gerx_db_dev_3 that need to be kept up to date with the latest data from the production database. The goal is to enable on-demand synchronization of these environments by leveraging a GitHub Actions workflow. To create a backup of your RDS PostgreSQL database using pg_dump, run a command similar to the follo…  ( 7 min )

As the CEO of Meteor Software for the past 3 years, I wanted to share some major exciting things about where we're heading.

Epic CEO Tim Sweeney says Apple is flat-out ghosting Fortnite’s latest App Store submission—“neither accepted nor rejected” it—putting this Friday’s big update at risk. Epic filed a new build on May 14 after Apple ignored their May 9 resubmission, even though Apple usually reviews 90% of apps within a day. A 2021 court injunction told Apple to “quit it” and follow the rules, but didn’t actually force Fortnite back on the store, so Apple’s free to leave the game hanging. Meanwhile, Sweeney’s been all over X pointing out Fortnite knock-offs that Apple approved (and some it quietly yanked), stoking fan outrage and shine a spotlight on the limbo. With zero word from Apple and a crucial update looming, iOS Fortnite players are left staring at a loading screen—and nobody knows what Epic will do next.  ( 3 min )

TL;DR: Samsung demoed a tiny 1.4-inch RGB OLED-on-Silicon panel packing a whopping 5,000 ppi—outclassing Apple’s Vision Pro (3,386 ppi) and Meta Quest 3—at SID Display Week. The microdisplay can hit 15,000 nits brightness at 120 Hz with 99% color gamut, effectively banishing the “screen door” pixel grid in VR. Beyond VR headsets, Samsung cranked a lower-density demo (4,200 ppi) to over 20,000 nits and notes the same tech could slot into a smartwatch. By building OLEDs onto silicon wafers, it uses chip-fab tricks to cram in ultra-tiny, super-bright pixels for next-gen wearables.  ( 3 min )

Max Mode in Cursor caught my attention because of how easy it is to enable—and how quietly it can start racking up costs. There’s no prompt, no permission gate, and no usage alert. It made me wonder: in an enterprise setup, how would we even know if someone turned it on? Cursor recently rolled out Max Mode, giving users access to their most powerful models—like GPT-4o and Claude Opus—with massively expanded context and smarter completions. It’s a great feature. But if you’re managing Cursor on an enterprise account, there’s a pretty big catch: anyone can turn it on, and it immediately starts billing your account. Here’s what Max Mode is, how it works, and why I think the lack of admin controls is a risky move. TL;DR: Max Mode in Cursor gives users powerful models with expanded context—but …  ( 6 min )

I got selected to move forward for a Software Engineer (Frontend) role with a foreign company from a cold DM and was given a test assignment. I delivered beyond the expected result, only to receive feedback from a review that seemed out of touch with current web development best practices, especially within the Vue 3 and Nuxt 3 ecosystem. A senior engineer who looked over my work remarked, “It’s clear you are better than the reviewer,” which inspired me to share this story. The review listed several shortcomings: No Composition API usage. No project architecture. Code repetitiveness. No cards stored in localStorage. Not following the Figma design. Bugs. Many of these points were vague or incorrect. Let’s examine each claim. Reviewer’s Claim: “No composition (Vue 3)” Reality: Every componen…  ( 5 min )

Hey Guys! This blog will make you understand what YAML is all about. Initially it was called Yet Another Markup Language, but later renamed to YAML Ain't Markup Language (a recursive acronym). YAML is the cleanest way to write configuration files. I'm guessing you already know we need config files for certain tasks while developing apps or working that DevOps magic. There are multiple ways to write configuration files such as XML, JSON, and TOML (plus several others), but YAML has some distinct advantages. These file formats make developers happy and help our data dance from server to server or client to server. They're primarily used for transmitting data between servers and clients, particularly in web applications. These are basic data formats for writing important stuff like secret fil…  ( 7 min )

Given a sorted array of numbers and a target sum, find the pair of numbers that add up to the target sum. Example: Input: [1, 2, 3, 4, 5, 6], Target: 10 Expected Output: [4, 6] (since 4 + 6 = 10) Let's explore two approaches to solve this problem: the straightforward brute force method and the more elegant two-pointer technique. The brute force approach is the most intuitive way to solve this problem. We'll check every possible pair of numbers in the array and see if they add up to the target sum. Use two nested loops to consider every possible pair For each pair, check if their sum equals the target Return the pair when found function findPairBruteForce(arr, targetSum) { for (let i = 0; i < arr.length; i++) { for (let j = i + 1; j < arr.length; j++) { if (arr[i] + arr[j] === …  ( 6 min )

The original WebAssembly project was jointly created by Mozilla, Google, Microsoft, and Apple in order to provide a common language runtime inside of the web browser. Following the path of web standards like HTML and CSS, the early Wasm creators decided to standardize the technology through the W3C. Nearly a decade later, the W3C standardization of WebAssembly is moving along well. WebAssembly 1.0 was complete…  ( 6 min )

🗥️ So I was casually doomscrolling X (yes, again)... when I stumbled upon a post by DEV Community that made my brain short-circuit: ✨ “ScoutDB turns plain English into MongoDB queries.” Wait, what?! You've got the data questions, but not always the query-fu: "Find all users who joined after Jan 2023 and liked more than 5 posts" Normally, you'd need to hand-craft some MongoDB incantation like: db.users.aggregate([ { $match: { joinDate: { $gte: ISODate("2023-01-01") }, likes: { $gt: 5 } } } ]) But what if you could skip the syntax pain? ScoutDB is like having a friendly AI that: ✅ Understands what you're trying to ask in English explore like a boss You type: Show me all posts with more than 100 likes created in the last 30 days ScoutDB replies with: db.posts.find({ likes: { $gt: 100 }, createdAt: { $gte: new Date(Date.now() - 30*24*60*60*1000) } }) Then maps the results and relationships for you in a visual explorer. No more $lookup headaches. No more crying in JSON. Saw this post by @thepracticaldev on X 👇 (I swear MongoDB and ScoutDB logos look like they just agreed to rescue all devs from query hell) 🗣️ English → MongoDB query? ✅ 🧠 Auto-maps your schema? ✅ 🎨 Visual canvas for data exploration? ✅ 🧣 Found it while doomscrolling Twitter?

Ever been in a daily Scrum where developers list empty words like “I coded the UI”? That’s a status update, not a sprint goal discussion. I’ve seen this confusion tank team focus for many years - and yes, I fix it every time. Sprint goals are Scrum’s core, yet developers often treat them as empty to-do lists. So let’s explore why developers confuse them with status updates, why sprint goals matter and how to fix the status update confusion to deliver real value. Why the confusion? A sprint goal is a clear outcome, like “Our team will allow users to enable gravitational anti-matter this sprint so that users can fly above water in their cars” or “We need to reduce technical debt to free up 25% of EC2 resources for other higher value added batches.” It’s the common why for the whole team t…  ( 5 min )

How NGINX Works Web Server Acting as a Reverse Proxy: The Middleman with Superpowers Here's how it works: A client sends an HTTP request to your web application. NGINX receives the request first, acting as the front-facing gateway. Based on its configuration, NGINX forwards the request to the appropriate backend server. The backend server processes the request (e.g., querying a database or rendering a web page) and sends the response back to NGINX. NGINX then returns the response to the original client. Key Advantages of Using NGINX as a Reverse Proxy: Load Balancing: Distributes traffic across multiple backend servers using strategies such as round-robin, least connections, or IP hash. Caching: Caches responses from backend servers to improve speed and reduce load. SSL Termination: H…  ( 5 min )

Introduction What is a Media Query? A media query is a CSS technique used to apply styles based on the device's characteristics, like screen width, height, orientation, or resolution. It helps make websites responsive. Syntax of a Media Query @media only screen and (max-width: 600px) { @media is the rule. only screen targets screen devices. (max-width: 600px) means it will apply when the screen is 600px or less. Inside the curly braces, you write the CSS rules that should apply. Common Media Query Breakpoints /* Small devices (phones) */ @media (max-width: 600px) { ... } /* Tablets */ @media (min-width: 601px) and (max-width: 992px) { ... } /* Laptops */ @media (min-width: 993px) and (max-width: 1200px) { ... } /* Desktops */ @media (min-width: 1201px) { ... } These are just examples. You can set custom breakpoints based on your design needs. Why Media Queries Matter Improves user experience across different devices Helps build mobile-friendly websites Allows you to customize layouts for different screen sizes My Practice Example /* Default style */ /* For mobile screens */ @media (max-width: 600px) { This changes the paragraph text size and color on smaller screens.

Since I started programming in Python, I have been fine using its standard library tool ‘venv’ for all of my work. You can create a venv like this: Python -m venv In the Python ecosystem, there are 4 famous tools for creating virtual environments: Standard library venv Virtualenv package Pipenv Conda environments I don’t want to go into depth about the differences between these tools; you can find useful compression articles for any of these tools against another one. For example this StackOverFlow thread A while ago, I started working on the project with 3 Python versions, 2.7 / 3.3 / 3.8.

If you don't know me yet, I have been working on ArkScript for nearly 6 years now. ArkScript is a scripting language in modern C++, running on a custom virtual machine (like Python or Lua), with the goal of having a syntax easy to learn and use, a C++ interface to embed it in programs, and decent performances (without trying to be as fast as Lua though, Mike Pall is a genius and did outstanding work on LuaJIT). A silly question that you shouldn't care about, unless the perceived slowness of the language is becoming a problem. Recently, I added more benchmarks to the language, and I was quite astonished to see that it was 1.5 times slower than Python on such a simple benchmark: (mut collection []) (mut i 0) (while (< i 1000000) { (append! collection i) (set i (+ i 1)) }) (mut sum 0) (s…  ( 10 min )

A large part of state management is data management - who owns data? How are limits kept track of? How is data allocated and destroyed? Our system has objects transparently migrating from server to server, so pointers are not an option - we have references instead. References can become invalid if the referenced object is destroyed, which leaves us with two options. Guarantee at the compiler and runtime level that all references remain valid while used, through lifetime tracking and the borrow checker, or force the programmer to handle the case of an invalid reference on every access. The latter is easier, if we introduce "owning references", which there can be only one of, and that are always valid. In fact, when an object is just declared as a field of another object - that's an owned re…  ( 5 min )

Ever wondered how JavaScript can fetch data from an API, wait for a timeout, and respond to user clicks, all without freezing your browser? It's not magic, it's the event loop. Even though JavaScript runs on a single thread, it handles multiple operations seamlessly using a clever system of background tasks, queues, and scheduling. Before we dive into how the event loop keeps things running smoothly, let’s break down the key components that make JavaScript’s async behaviour possible. Call Stack: Web APIs / Node APIs: These are provided by the browser or Node.js, things like setTimeout, fetch, DOM events, etc. They run asynchronously outside the main thread. Task Queue: After a Web API finishes (like a setTimeout), it sends the callback to the Task Queue. Microtask Queue: For things like Pr…  ( 4 min )

"Honest disagreement is often a good sign of progress." - Mahatma Gandhi. I saw that quote the other day, and it sort of lodged itself in my brain. I’m a pretty heavy YouTube consumer – it’s where I get news, learn stuff, find entertainment, the whole nine yards. And lately, watching hours of content, I’ve started to notice something… a kind of invisible wall that seems to go up around certain creators. You know how it is. You find a creator you vibe with. Their takes are fresh, or funny, or they just explain things in a way that clicks. So you subscribe, hit the bell, all that. And then you scroll down to the comments. And often, especially with more established channels, it's just… a sea of agreement. Pure affirmation. "You're so right!" "This is exactly what I was thinking!" "Best chann…  ( 5 min )

Javascript is one of the core technologies of the World Wide Web, alongside HTML and CSS.It's a high-level programming language used to add interactivity to web pages.Before JavaScript, webpages were static — they displayed content and provided hyperlinks which enabled the user to navigate through the Web, but offered little in terms of user interaction or dynamic behaviour.JavaScript changed this by enabling developers to create dynamic, responsive web experiences, allowing real-time content updates, interactive forms, and engaging user interfaces directly in the browser. Each web browser has its own JavaScript engine that interprets and executes JavaScript code, converting it into machine language to run on the computer's hardware.This javascript engine plays a pivotal role in providing …  ( 6 min )

Web apps are under siege in 2025. Cybercriminals are more sophisticated, APIs are under constant attack, and traditional authentication methods like session cookies or static API keys just don’t cut it anymore. According to Verizon’s 2023 Data Breach Investigations Report, 74% of breaches involved the human element—including social engineering, errors, and misuse of credentials. That means the majority of attacks could have been mitigated with stronger access controls and token-based authentication.

In 2025, we finally made the call — Sails.js is out of our stack. We tried hard to keep Sails alive. We added TypeScript, wrote custom types, wrapped controllers, hacked the models, and even considered forking it to modernize the whole thing. But the deeper we went, the more obvious it became — the foundation just isn't made for today. Outdated patterns, broken dependencies, Docker images with critical vulnerabilities... The project is barely maintained — just version bumps for security. It’s no longer a tool for modern development. Our main project today is RestoApp — an open-source platform for restaurants, food delivery, and retail. A big part of it is the admin panel. Originally, we started from sails-hook-adminpanel by Kostya Zolotaryov — and we’re genuinely thankful to him for that. It gave us a solid starting point. Over 8 years, we evolved it a lot — changed frontend stacks multiple times — and today, it’s become a fully independent, configurable, and open-source admin system. No longer tied to Sails, no specific ORM, no locked-in logic. Just a single config file — and it works. Meet Adminizer 📌 What’s next? So yeah — this is our goodbye to Sails. Now — we move forward.  ( 3 min )

We store data to record the state: A password change, an order made, an order delivered and etc. Such things can be seen as stand-alone events or, in many cases, they are part of a step in a process. And, it's common to see those things be chucked into a single table. All those columns can result in models that bloat to 1000s of lines. When looking at a model like that, you may have an urge to group all columns and methods to make sense of what is going on. It's tiring enough doing it once, but it becomes a bigger issue when you and others have to go through the same process each time. In situations like this, proxy models can become invaluable!

ORM technology indeed simplifies basic CRUD operations, but it also has many limitations when dealing with complex calculations. Hibernate’s HQL is notably inadequate, making it difficult to implement dynamic column calculations and multi-layer associations. While JOOQ improves flexibility through its DSL, its grouping calculations require multi-layer nesting, leading to more verbose code than native SQL. esProc SPL is like a “plug-in” for data computation! To write a multi-layer JOIN based on dynamic conditions, you had to use chain calls in Java for half an hour with JOOQ. Now you can implement this in just a few lines of SPL script, and its syntax is more intuitive than SQL. For example, calculating ‘top 3 sales by department’, which even requires nesting in SQL: SELECT dept, name FROM …  ( 5 min )

Automation Isn’t Enough Anymore For decades, business automation has been a reliable tool for improving efficiency, moving emails, copying data, and sending alerts. But today’s business environment is faster, more data-driven, and increasingly unpredictable. Traditional rule-based automation is struggling to keep up. Traditional automation tools like Zapier, Make, and basic RPA (Robotic Process Automation) platforms helped companies automate repetitive tasks. These systems operate on "if-this-then-that" logic. However, they have significant limitations: Lack of Adaptability: Even small deviations, like a changed email format, can cause failures. No Contextual Understanding: They cannot interpret unstructured data, sentiment, or nuance. Constant Maintenance: Business process changes requi…  ( 6 min )

Hi! I’m Kostiantyn, a 14-year-old fullstack developer with solid skills in JavaScript and TypeScript. Over the last few months, I’ve earned more than $3,000 working on real projects and freelancing — all before even finishing high school. Mastering JavaScript/TypeScript and Next.js for fast, scalable frontend and backend development. Building simple SaaS projects that solve real problems and bring real income. Learning backend basics with Node.js and NestJS, since this stack is in huge demand. Why I Put Go on Hold I started learning Go because it’s popular for backend and microservices. But quickly realized it doesn’t fit my current goals. Go requires more time to master and lacks the quick feedback loop I get with JavaScript and Node.js. For now, I prioritize skills and tools that help me earn money faster and build complete products. To keep building SaaS products and freelance projects that improve my skills and generate income. Practical experience and fast results are key at my age. I’ll continue focusing on JavaScript, Next.js, and NestJS, then later consider other backend languages like Go or Rust when I’m ready for bigger challenges. Thanks for reading!

A Nostalgic Story About 8 years ago, when I was just a kid, I began my coding journey with a school book — you know, the classic QBASIC chapter. I learned about variables, conditional statements, and control flow, writing small programs like basic calculators and whatnot. But then, there was this one section at the end... That single section changed everything. I learned how to draw rectangles, circles, and all kinds of shapes on the screen. And then my brain started buzzing with ideas. You know what’s coming next… my very first game. If you’re a tech person, you’re probably thinking: “Who the hell makes games in QBASIC?” 😅 Well… an innocent 11-year-old me did. I didn’t know how to Google things back then (heck, I barely knew what Google was). But somehow, with a school textbook and sh…  ( 4 min )

Description: Learn the basics of key HTML tags and how to build your very first simple webpage with easy-to-follow code examples. Introduction Figure: A historical newspaper front page (Hilo Tribune). HTML stands for HyperText Markup Language, and it’s the foundation of every web page. It uses code (tags inside ) to tell your browser how to display content. This is similar to how a newspaper uses headlines and sections to organize information. For example, the image above shows a newspaper with a big headline and columns of text. In HTML, we create structure with heading tags ( through ) and paragraph tags ( ), just like the title and stories in a newspaper.

How Java Stores Data in Memory — Primitives vs Non-Primitives Java is a statically typed language, which means every variable’s type must be known at compile time. This allows the JVM (Java Virtual Machine) to allocate memory efficiently and enforce type safety during execution. Primitive types are the building blocks of data in Java. They have fixed memory sizes and are stored in the stack. The value of a primitive can change, but its size does not. Type Size Description byte 1 byte Smallest integer (–128 to 127) short 2 bytes Short integer int 4 bytes Default integer type long 8 bytes Large-range integer float 4 bytes Single-precision float double 8 bytes Double-precision float char 2 bytes Unicode character boolean 1 bit* True or False (handled as 1 byte internall…  ( 5 min )

🚫 Top 10 Common Mistakes in Kotlin Programming Treating nullable types as non-null without checks. ✅ Use ?., ?:, and !! carefully. Prefer safe calls and smart casting. !! (Not-null Assertion) Using !! too much can crash the app with NullPointerException. ✅ Use null-safe operators and proper null checks instead. var Instead of val Declaring variables as mutable (var) when they should be immutable (val). ✅ Prefer val for safer, more predictable code. Using apply, let, also, etc., without understanding context. ✅ Choose the right scope function for the right purpose. == and === == checks structural equality, === checks reference equality. ✅ Know when to use each depending on what you're comparing. Not using try/catch when calling risky operations (e.g., parsing, IO). ✅ Always handle exceptions gracefully. Launching coroutines without a proper scope or dispatcher. ✅ Use structured concurrency: lifecycleScope, viewModelScope, etc. Reinventing functions already available (e.g., filter, map, groupBy). ✅ Explore and master Kotlin’s powerful standard library. Not converting Java-style code to idiomatic Kotlin. ✅ Embrace Kotlin syntax, avoid Java habits (e.g., setters/getters, verbose loops). Explicitly declaring types unnecessarily. ✅ Let the compiler infer types where obvious – cleaner and shorter code. Generate exclusive photo for your post  ( 3 min )

Introduction If you're encountering issues with TypeScript where your build fails because of Promise.allSettled, you're not alone. The error messages you're receiving, such as Property 'reason' does not exist on type 'PromiseSettledResult', can be frustrating. Understanding how TypeScript handles Promise results is crucial for resolving these errors effectively. Understanding Promise.allSettled The method Promise.allSettled() is a Promise method that takes an iterable of Promises and returns a single Promise that resolves after all of the given Promises have either resolved or rejected, with an array of objects that each describe the outcome of each Promise. Each object in the array has a status property, which can either be 'fulfilled' or 'rejected'. When a Promise is fu…  ( 4 min )

As a beginner in coding, it's perfectly natural to have questions about how things work, especially when dealing with dynamic arrays in C++. In your code, you have set up a dynamic array that can grow as needed, and you're using a couple of key concepts to manage memory and data. Let's dive into your questions and break down how your code operates, while also discussing the underlying principles of dynamic memory allocation in C++. How Does the Dynamic Array Resize Work? You mentioned that you set the initial size of the array to 5 and that it can increase to 10, yet you are able to store up to 20 numbers. This is a great point of confusion for newcomers. The way your code works involves both the capacity variable and the dynamic allocation of memory. Dynamic Memory Allocation Initially, y…  ( 5 min )

Conceptual Comparison: Developer Mindset, Responsibility Separation, and Task Decomposition Building on the previous article, this one will explore the shift in developers' mindset when transitioning from API development to A2A development. Developer Mindset Shift: Function-Oriented vs. Agent-Oriented. Traditional development often involves thinking in terms of functions or API call sequences: starting from input, invoking services step-by-step, and finally producing output. Developers act as "orchestrators," controlling every step. In contrast, agent-oriented architecture requires a new mindset—designing a community of agents, each responsible for a subtask and interacting via messages and protocols. Instead of scripting flows directly, developers configure systems of autonomous agents,…  ( 5 min )

Understanding == vs Equal() for comparing time When working with time values in Go, one of the most common operations is comparing two timestamps. However, this seemingly simple task can lead to subtle bugs if you're not aware of the differences between using the equality operator (==) and the Equal() method. The equality operator (==) compares all fields of the time.Time struct, including the location information and the monotonic clock reading. This means two times that represent the exact same moment might not be considered equal if they were created in different ways or have different internal representations. t1 := time.Date(2023, time.January, 1, 0, 0, 0, 0, time.UTC) t2 := t1.In(time.FixedZone("UTC-8", -8*60*60)) // These times represent the same instant but have different locati…  ( 13 min )

The first phase of the project, a high-fidelity interactive prototype, is finally complete! This iteration is a sort of detailed rough draft showcasing the design and functionality of the website, mostly using placeholder content. The final straw for this iteration was the addition of the Gallery page. public/gallery/ directory. This means images can be uploaded directly into this folder, and they'll automatically appear with the next site build. To achieve this functionality, the /gallery route is rendered dynamically on the server: export const dynamic = 'force-dynamic'; Rendering the page server-side allows the use of Node's built-in fs module to directly access files on the server: const galleryDir = path.join(process.cwd(), 'public', 'gallery'); let allFiles; try { allFiles = await fs.readdir(galleryDir); } catch (e) { console.error('Could not read gallery directory:', e) allFiles = []; } // Filter to only image files (jpg, png, gif, etc.) const images = allFiles.filter((file) => /\.(jpe?g|png|gif|webp|avif)$/i.test(file) ) I'll be utilizing Statsig to implement feature flags which will allow us to hide and show seasonal Hero sections without interacting with code.

Laravel is one of the most popular PHP frameworks, and for good reason—it's elegant, expressive, and comes with many built-in security features. But just because Laravel provides the tools doesn’t mean you’re automatically safe. Whether you're building an MVP or maintaining a large-scale application, security must be a priority. Here are 15 Laravel security best practices every developer should follow in 2025: Always keep Laravel, its dependencies, and PHP up to date. Laravel releases often include security patches and improvements. Laravel's Eloquent ORM and query builder automatically use prepared statements. ✅ Safe: $users = DB::table('users')->where('email', $email)->get(); ❌ Avoid: DB::select("SELECT * FROM users WHERE email = '$email'"); Escape all output using Blade syntax: {{ $us…  ( 4 min )

As a beginner in C++, you might find yourself needing to convert strings to integers, for which you have already encountered functions like atoi and strtol. While atoi is straightforward, it lacks error checking, making strtol a more robust choice due to its ability to handle conversion errors properly. In this article, we will dive deeper into understanding *temp and &temp when using strtol, clarifying how they work and when to use each. Why Use strtol for String to Integer Conversion? The strtol function is preferred for converting strings to long integers because it provides better error handling. It allows you to detect whether the conversion was successful and if the entire string was converted. Here’s a quick overview of how to use strtol: Prototype: long strtol(const char *nptr, cha…  ( 5 min )

SQL queries are an important tool for retrieving data from databases and are widely used in the field of computer science.

Usage: It is widely used for summarizing data and can be combined with aggregate functions. SELECT department, count(*) AS emp_count Note: Aggregation is useful for identifying patterns and uncovering hidden trends in the data. Usage: Joins are used to com…  ( 4 min )

Here is a quick way to avoid nil errors and get better failures in Ruby and Ruby on Rails. Convert hashes with known keys into Structs: data = { a: 1, b: 2, c: 3} ... MyData = Struct.new(:a,:b,:c) data = MyData.new(a: 1, b: 2, c: 3) Structs will throw if you introduce a typo instead of returning nil. This tightens your feedback loops and reduces debugging time. hash[:d] => nil struct[:d] => in 'Struct#[]': no member 'd' in struct (NameError) That is cool. What about in more fluid situations like user input? You can convert arbitrary incoming hashes into known structs quickly with the following: params = {a: 1, b: 2, c: 3, x: 9, z: 0} MyData.new(**params.slice(*MyData.members)) While Structs have much the same interface as hashes, there are some tricky differences. Hash#each is equivalent to Struct#each_pair. Hash#keys is equivalent to Struct#members. There is no equivalent to Hash#fetch.  ( 3 min )

Tokenization could open new opportunities for retail investors to access traditionally restricted asset classes, according to Johann Kerbrat, senior vice president and general manager of Robinhood Crypto, who called it “very important for financial inclusion.” Speaking at the Consensus 2025 event in Toronto, Kerbrat said that some real-world assets, such as real estate and private equity, are available only to up to 10% of the US population. “You need to be an accredited investor to invest in private equity right now,” he said. “How many people can afford a house or an apartment in New York?” he elaborated. “But you can get a piece of it with fractionalization, through tokenization. And so we think it makes it a lot easier to be exchanged, a lot more accessible for everybody.” Robinhood'…

The Filecoin Foundation and Lockheed Martin Space have successfully transmitted data in space using a version of the InterPlanetary File System (IPFS) on a satellite orbiting Earth, Marta Belcher, president of the Filecoin Foundation, told Cointelegraph.  Filecoin and Lockheed Martin adapted the system for use in space and successfully tested it, Belcher said during the Consensus 2025 conference in Toronto. The IPFS enhances privacy and security compared to traditional web protocols, such as HTTP, by identifying data based on its content rather than its location. This has additional benefits for data transmission in space, Belcher said. “The architecture is well-suited to space because it reduces delays, compensates for data corruption caused by radiation, and enables cryptographic verific…

At least one partner at Sequoia Capital was reportedly impacted by the recent data breach among Coinbase users, suggesting that data from others at the venture capital firm may also have been compromised. According to a May 16 Bloomberg report, Sequoia Capital Managing Partner Roelof Botha’s personal information available through his Coinbase account was stolen after a group of cybercriminals bribed the exchange’s support agents for access to user data. Though Botha had not publicly disclosed his net worth, estimates suggested he had hundreds of millions of dollars in assets. Coinbase disclosed the data breach in a May 15 blog post, saying that some of its users had been targeted with social engineering attacks after the criminals had access to their personal account information. The company said the group attempted to extort $20 million in exchange for not disclosing the breach, which Coinbase rebuffed. Though the extent of the breach was still unknown, another Bloomberg report suggested that the same type of attacks targeted users at Kraken and Binance. Cointelegraph reached out to representatives from both exchanges but had not received any response at the time of publication. This is a developing story, and further information will be added as it becomes available.

Solv Protocol has launched a yield-bearing Bitcoin token on the Avalanche blockchain, giving institutional investors more exposure to yield opportunities backed by real-world assets, or RWAs. On May 16, the protocol unveiled SolvBTC.AVAX, a token that connects Bitcoin (BTC) to real-world assets like US Treasurys and private credit offered by BlackRock and Hamilton Lane.  The new token was developed through a seven-way partnership involving Solv, Avalanche, Balancer, Elixir, Euler, Re7 Labs, and LFJ, the company said.  Solv Protocol founder Ryan Chow said the token is a way to link Bitcoin to “real-world economic cycles” in uncorrelated assets such as US government bonds and private credit, as opposed to BTC’s typical boom-and-bust four-year cycle. The token uses a multi-protocol strategy t…

A federal judge has sentenced Eric Council Jr., one of the individuals responsible for posting a fake message announcing regulatory approval of spot Bitcoin exchange-traded funds, to 14 months in prison. Following a May 16 hearing in the US District Court for the District of Columbia, the Justice Department announced that Council would serve 14 months in prison after pleading guilty to one count of conspiracy to commit aggravated identity theft and access device fraud. He was part of a group that compromised the X account of the US Securities and Exchange Commission (SEC) in January 2024 and said the regulatory body would be approving spot Bitcoin (BTC) ETFs. Prosecutors had requested that the judge impose a two-year sentence, while Council’s lawyers asked for one year and one day. Court filings showed he earned roughly $50,000 through SIM swap attacks like the one that compromised the SEC’s X account — funds likely subject to forfeiture. This is a developing story, and further information will be added as it becomes available.

Christy Goldsmith Romero of the US Commodity Futures Trading Commission (CFTC) will step down on May 31, leaving three seats open at the financial regulator. In a May 16 announcement, Romero said her last day at the agency would be on May 31, ahead of her initial plans to leave if the Senate confirmed former commissioner Brian Quintenz as the new chair. Her departure will come just one day after Commissioner Summer Mersinger is expected to step down to join the crypto advocacy organization the Blockchain Association as CEO. “It has been a tremendous honor to conclude my 23 years of federal service at an agency with such an important mission to ensure that financial markets perform their critical role in the US and global economies,” said Romero. Romero and Mersinger’s upcoming departures would leave the CFTC with only two Senate-confirmed members: acting chair Caroline Pham and Commissioner Kristin Johnson, each taking one Republican and Democratic seat, respectively. The shakeup in leadership gives President Donald Trump the opportunity to pick two more commissioners after the Senate addresses Quintenz’s nomination. This is a developing story, and further information will be added as it becomes available.

Opinion by: Megan Knab, CEO, Franklin Payroll There are few historical examples of such a massive about-face for an industry, from banks debanking crypto businesses to now embracing stablecoins. If you talk to most crypto startup founders or companies with crypto on the balance sheet, they will all have war stories about finding, applying for and maintaining bank accounts.  Over the past three years, over half of debanking complaints have been lodged against four American banks — Bank of America, JPMorgan, Wells Fargo and Citibank. Now, as the policies that discriminated against the crypto industry, like “Operation Chokepoint 2.0” and the recision of controversial accounting rule SAB 121, have been repealed, a new openness to blockchain technology from the finance sector is possible.  It i…

The European Union’s Markets in Crypto-Assets regulation — better known as MiCA — is now in its critical implementation phase. Designed to unify crypto regulation across all 27 EU member states, MiCA promises clarity, consumer protection and long-term market stability. But as implementation begins, cracks are already showing. In this week’s episode of Byte-Sized Insight, we explore the key provisions of MiCA now in force, particularly around stablecoins, and why some of the largest players in the market are refusing to comply. As of January 2025, crypto asset service providers (CASPs) began acquiring licenses to operate legally within the EU. A transitional or “grandfathering” period allows existing firms up to 18 months, depending on the member state, to comply. Still, with deadlines app…

As cryptocurrency gains in popularity and price, some criminals are taking to violent measures to steal funds from high-profile crypto holders. Jameson Lopp’s GitHub repository, which logs such incidents, has recorded 22 “$5 wrench” attacks on crypto holders in 2025 alone. The moniker comes from the crude and violent methods perpetrators use to compel crypto holders to hand over their bags.  In many cases, local law enforcement can intervene before anyone is harmed and funds are lost. But there is a growing trend of increasingly violent and successful attacks, some of which have resulted in permanent harm and even death. The most recent incident in Paris, France compelled the French Ministry of the Interior to hold a meeting to address the rising trend. Here are just seven of the most high…

Why did Fantom reinvent itself as Sonic? Fantom was one of the pioneers of the directed acyclic graph (DAG) design for distributed ledgers. It featured fast finality and transaction fees of a fraction of a cent. However, Fantom relied on the Ethereum-derived account storage model and the EVM, which led to bloated storage and slow execution times. To address these bottlenecks and implement numerous other updates, the team behind Fantom rolled out Sonic, a fully independent new blockchain network.

Ethereum Merge architect Justin Drake told Cointelegraph that it would be cheaper to launch a 51% attack on Bitcoin than on Ethereum. Drake said it would be “much cheaper to 51% attack Bitcoin” and that it would cost “on the order of $10 billion.” Drake led work on Ethereum’s proof-of-stake (PoS) implementation and was a principal architect in the Merge (the full PoS transition event). His remarks echo a May 14 X post by Grant Hummer, the co-founder of Ethereum-focused marketing and product company Etherealize. In the post, Hummer said that Bitcoin “is completely screwed because of its security budget.” Hummer claimed it would cost $8 billion to run a successful 51% attack, and said a successful attack is “virtually certain” when the cost slips to $2 billion.

The 20-member Northern Mariana Islands House voted 14-2 to undo Governor Arnold Palacios’ April 11 veto of the bill, which allows the Tinian local government to issue licenses to internet casinos and includes a provision for the Tinian treasurer to issue, manage and redeem a “Tinian Stable Token.”  The territory’s nine-member Senate had revived the bill on May 9, voting 7-1 in a two-thirds majority to override the veto, which then needed a two-thirds majority in the House to pass. Representative Marissa Flores (top left) had urged for “thoughtful deliberation” on the internet gaming and sta…

Jason Guthrie, head of product at asset manager WisdomTree, says he’s optimistic despite a noticeable lack of hype that typically comes along with a crypto bull run.  There hasn't been a “really frothy use case that has typically driven these market cycles previously,” such as initial coin offerings (ICOs), non-fungible tokens (NFTs), or DeFi lending, Guthrie told Cointelegraph at Consensus. “This time, we’ve continued to see the asset class gathering value, we’ve continued to see the companies that are built on this technology, growing revenue, growing client bases, continuing to innovate without really hanging their hat on one of these frankly less than useful use cases,” he said.

Another 12 people have been charged for their involvement in a $263 million crypto crime spree that stole 4,100 Bitcoin from a Genesis creditor last August, along with a string of break-ins and money laundering.  The 12 new names, included in a superseding indictment, add to charges originally brought against the main defendant in the case, Malone Lam, on Sept. 19, 2024, the Department of Justice noted in a May 15 statement. Jeandiel Serrano was named a defendant in the initial indictment but was not included in the superseding one. The DOJ said several defendants have been arrested, while two others are believed to be living in Dubai. Many of the suspects, with aliases like “Goth Ferrrari” and “The Accountant,” come from California, mostly aged between 18 and 22.  The group allegedly beg…

Elon Musk’s artificial intelligence firm xAI has blamed an “unauthorized modification” to the Grok chatbot’s response, causing it to generate responses mentioning political and racial tensions in South Africa.  On May 16, xAI provided an update on the Grok AI chatbot’s inflammatory responses, stating that on May 14, “an unauthorized modification was made to the Grok response bot’s prompt on X.” “This change, which directed Grok to provide a specific response on a political topic, violated xAI’s internal policies and core values,” it added. The firm stated that it had conducted a thorough investigation and is implementing measures to enhance the AI chatbot’s transparency and reliability. Grok generated responses on May 14, mentioning a “white genocide” conspiracy theory in South Africa when…

Deepfake-assisted hackers are now targeting US federal and state officials by masquerading as senior US officials in the latest brazen phishing campaign to steal sensitive data.  The bad actors have been operating since April, using deepfake voice messages and text messages to masquerade as senior government officials and establish rapport with victims, the FBI said in a May 15 warning.  “If you receive a message claiming to be from a senior US official, do not assume it is authentic,” the agency said.   If US officials’ accounts are compromised, the scam could become far worse because hackers can then “target other government officials, or their associates and contacts, by using the trusted contact information they obtain,” the FBI said.  As part of these scams, the FBI says the hackers a…

US federal prosecutors are pressing ahead with their case against Tornado Cash founder Roman Storm, but will drop a small part of their indictment after the Department of Justice rolled back its crypto enforcement last month.

Deputy Attorney General Todd Blanche’s April memo said the Justice Departmen…

Global foreign exchange and payments platforms are lobbying hard against stablecoins, which stand to significantly disrupt their business models, investor Kevin O’Leary said during a keynote address at Consensus 2025. Legacy forex and payments platforms often extract large fees for servicing cross-border cash transfers and stand to lose out on revenue if regulated stablecoins become accepted as a cheaper, faster alternative, O’Leary said at the Toronto conference.  “Currency trading is a multi-trillion dollar market — and it’s old and ugly and inefficient,” O’Leary said, adding that “[ t]he biggest threat to that monopoly or oligopoly is a regulated stablecoin.”  “Once that’s approved, the multi-trillion dollar FX market becomes efficient, transparent, and inexpensive,” he said.  Kevin O’…

Coinbase chief legal officer Paul Grewal addressed some of the concerns raised by US lawmakers and industry leaders around President Donald Trump’s crypto ventures, and how they may affect related legislation.

Though Grewal said there were disputes over “substantial issues that need to be addressed” in the bill, he hinted that Trump’s involvement in the industry was a “complicating factor.”  “The discussion around the president's support for a certain memecoin or two and other efforts does add a certain level of challenge to the effort to g…

Key takeaway: Bitcoin’s struggles to overtake the $105,000 level as US macroeconomic headwinds remain a challenge. Steady inflows from institutional investors and the strength of the $100,000 support point to growing confidence in Bitcoin.

Asset tokenization is set to accelerate the movement of capital across traditional markets, according to Chainlink co-founder Sergey Nazarov.

Bitdeer Technologies Group reported a 41% year-over-year drop in revenue to $70.1 million for the first quarter of 2025, the Bitcoin miner said on May 15.  The Singaporean company clocked an operating loss of $3.2 million for the quarter, down from a $34.1 million profit during the same period last year, its earnings release said.  However, Bitdeer reported a Q1 net income of more than $400 million, largely driven by gains on convertible notes and warrants issued to stablecoin issuer Tether in 2024.

The slow adoption of stablecoins in Canada has some local crypto industry observers concerned that the country is falling behind. The Canadian Securities Administrators (CSA) classified stablecoins as “securities and/or derivatives” in December 2022 after the FTX debacle that shook markets and turned many lawmakers against the crypto industry. Regulating stablecoins as a security has seen few local stablecoin issuers arise, but in the United States and the European Union, softening regulations have seen significant growth in the stablecoin market. This makes Canada, observers say, less competitive with other jurisdictions.  Of particular concern is the perceived gap in peer-to-peer (P2P) payments in Canada, which stablecoins are uniquely qualified to fill.  Stablecoins globally have grown …

Coinbase has reportedly fired a group of customer support agents following their alleged involvement in social engineering attacks on users. The contracted agents were based in India. According to a May 15 Fortune interview, Coinbase's chief security officer, Philip Martin, said the company flagged customer support contractors who allowed scammers access to user data, suggesting they could be Indian nationals. The CSO’s comments came after some crypto users reeled from attempted phishing attacks using their Coinbase data, which the exchange estimated could cost them between $180 million and $400 million in remediation and reimbursement. Qiao Wang, a core contributor to Alliance DAO, said in a May 15 X post that he may have been a victim of one of these attacks. He said a scammer notified him his Coinbase account had been compromised, asked him to verify his personal information, to which the criminals likely had access through the compromised agents, and requested he withdraw all his funds to a “Coinbase self-custodial wallet.” “I called them out at the end of the call telling them they need to step up their game [...],” said Wang on X. “They told me that had made $7m that day.” Cointelegraph reached out to Martin and Coinbase for comments, but had not received responses at the time of publication. This is a developing story, and further information will be added as it becomes available.

Key takeaways: Spot Bitcoin ETF inflows dropped over 90% from $3 billion to $228 million in four weeks. While strong ETF inflows often drive Bitcoin rallies, recent data shows price movements can occur independently. Despite short-term selling pressure, long-term BTC whale buying suggests a potential continuation of the BTC uptrend. The Bitcoin (BTC) market posted a 90+% drop in spot BTC exchange-traded fund (ETF) inflows, falling from $3 billion in the last week of April to just $228 million this week. Historically, a slowdown in ETF inflows has impacted BTC price, notably when daily inflows averaged over $1.5 billion for consecutive weeks. To understand the potential impact on Bitcoin, let’s examine four key periods of significant spot ETF activity and their correlation with BTC pri…

Opinion by: Jennifer Dodgson, co-founder of KIP Protocol and Eigenform AI The puppet show is ending. The Brookings Institution found that generative artificial intelligence may disrupt at least 50% of tasks performed by more than 30% of all workers. The same study also estimates that genAI may affect at least 10% of tasks performed by approximately 85% of the human workforce. The TL;DR from these stats? AI’s effects are likely to be both broad and deep. If AI doesn’t already scare you, self-learning AI agents that autonomously achieve goals may fix that. Forget your sanitized ChatGPT conversations and bland AI assistants. Superior agents are AI that autonomously achieve human-set objectives by any means necessary.

Understanding the 10-year Treasury yield: Definition and importance The 10-year Treasury yield is the interest rate that the US government pays to borrow money for 10 years. When the government needs cash, it issues bonds called Treasury notes, and the 10-year note is one of the most watched. The “yield” is the annual return you’d get if you bought that bond and held it until it matures. It’s expressed as a percentage, like 4% or 5%. Think of it as the government saying, “Hey, lend me $1,000, and I’ll pay you back in 10 years with some interest.” That interest rate and the yield move up or down based on demand for the bonds, inflation expectations and the overall economy. Because US Treasurys are considered safe (the government isn’t likely to def…

As more and more businesses are impacted by tariff volatility, some executives, like Ridhima Kahn, vice president of business development at Dapper Labs, are viewing the assault on the cost of physical goods as another use case for digital markets powered by blockchain to shine. “I’m seeing a lot of brands rethinking where revenue and fan engagement come from,” Kahn said during an exclusive interview with Cointelegraph. “A lot of franchises, like the ones we work with — NBA, NFL, Disney — have already had years of success with digital collection, and we’re seeing a lot of brands express interest in digital collectibles as a way to engage with fan bases at a time when physical costs are riskier and unknown.” Propelling brands to take a deeper look at digital merch is the desire to better un…

One key innovation under discussion is trustless lending — allowing users to borrow agai…

Key points: US treasuries and foreign capital “repatriation” make a recipe for $1 million BTC, says Arthur Hayes. Europeans face tightening capital controls, inviting a recommendation to take back control of personal funds. Seven-figure BTC price targets are already gaining traction.

For Hayes, shifting capital controls worldwide, as well as US treasury “devaluation,” mean that Bitcoin wi…

Prominent short-seller Jim Chanos, once a vocal critic of Bitcoin and cryptocurrencies, revealed a new trading play that involves shorting shares of Strategy (formerly MicroStrategy) and buying Bitcoin. At the Sohn Investment Conference in New York, Chanos told CNBC he’s “selling MicroStrategy stock and buying Bitcoin.” The investor described the move as buying something for $1 and selling something for $2.50, referring to what he sees as a significant price mismatch. Chanos argued that Strategy is selling the idea of buying Bitcoin (BTC) in a corporate structure, and that other companies are following suit in hopes of receiving a similar market premium. Chanos said this was “ridiculous.” He described his trade as “a good barometer of not only just the arbitrage itself, but I think of reta…

Digital assets like stablecoins are the “perfect” financial instrument for real-time collateral management, according to a recent pilot by DTCC Digital Assets, which suggests that digital assets, particularly stablecoins, could modernize and simplify this critical function. “Digital assets really are the perfect use case for collateral management, whether it be uncleared derivatives,…

Opinion by: Yat Siu, executive chairman and co-founder, Animoca Brands A discussion on digital property rights, copyright, intellectual property, the open metaverse, AI and value without physical form. When I attend conferences and similar public events, someone almost always approaches me to ask how cryptographic tokens (fungible or non-fungible) can have value even though tokens are virtual and do not exist in the physical world. It's a surprisingly common question, especially one-on-one. Virtual objects like NFTs and cryptocurrencies are both digital and intangible; their existence is not based in the real (physical) world, and (unlike digital currencies) they generally do not have backing by real-world institutions.  The ability to have value (specifically, monetary worth) is crucially…

Some criminal organizations are yet to receive the memo — crypto is traceable — and could explain the recent string of crypto-related kidnappings, says Chainalysis CEO Jonathan Levin.  Law enforcement has been increasingly successful at tracing stolen funds and crypto ransom payments, resulting in a “lot of arrests,” Levin said during the 2025 Consensus crypto conference, covered by Cointelegraph. “For whatever reason, there is a perception that’s out there that crypto is an asset that is untraceable, and that really lends itself to criminals acting in a certain way,” he said.  “Apparently, the know that crypto is not untraceable hasn't been received by some of the organized crime groups that are actually perpetrating these attacks, and some of them are concentrated in, you know, France, b…

European law enforcement in January arrested 17 suspects of a “mafia crypto bank” who are said to have laundered over 21 million euros ($23.5 million) in crypto for criminal entities in China and the Middle East.
